The 12 May Karachi riots, also known as Black Saturday riots, were a series of violent clashes between rival political activists in Karachi. The violence resulted in 58 deaths. The unrest began as the recently suspended chief justice of Pakistan Iftikhar Chaudhry arrived at the Jinnah International Airport on 12 May 2007. Gunfights and clashes erupted across the provincial capital as lawyers, Pakistan Peoples Party (PPP), Awami National Party (ANP), Pakistan Tehreek-e-Insaf (PTI), and Pashtunkhwa Milli Awami Party (PMAP) activists, who supported the judge, and the pro-government Muttahida Qaumi Movement (MQM) activists took to the streets against each other. Pakistan Muslim League Quaid-e-Azam (PMLQ) and MQM party workers, with support from military dictator Gen. Pervez Musharraf, were accused of launching highly coordinated attacks against lawyers, ANP, PTI, PPP activists and news channels, especially Aaj News. Government machinery was used to block all major roads. Police was accomplice and a silent spectator to the violence. News media was attacked at Guru Mandir (Business Recorder Road) when MQM activists began firing at Aaj News headquarters which was shown on live television. Most of the 58 killed were part of opposition parties supporting Chaudhry.

Chaudhry's supporters had announced a public rally to welcome the judge while at the same time, the MQM also announced a demonstration of their own to protest against the politicisation of the issue of the judge's suspension. The MQM made plans to deliberately converge at the mausoleum of Muhammad Ali Jinnah where the chief justice was to make an appearance to address a lawyers' convention and a bar association meeting at the 50th anniversary of the Sindh High Court Bar Association.

Lawyers' Movement Before the citywide riots escalated, several roads were cordoned off and all routes to the airport were blocked to avoid clashes between groups. In the carnage that ensued, armed groups did a lot of damage. Cars were burnt and buildings smashed into while the ensuing gunfights left more than 40 people killed with several hundred injured and arrested. The violence continued for several days, culminating in events that led to the historic Lawyers' Movement.

Several lawmakers and analysts have since questioned the incompetence of the city's security apparatus on the day of the riots and the complicity of MQM in giving rise to the riots. The MQM officially denied starting the chaos and blamed it on the PPP, ANP, PMAP, Punjabi Pakhtun Ittehad (PPI), and Pakistan Muslim League (N) (PML-N) activists.

Background

In the first few months of 2007, several conflicts had already raged between chief justice Iftikhar Muhammad Chaudhry and the Pakistani government, particularly with regard to the Pakistan Steel Mills corruption case where the chief justice ruled against the sale of the state-owned steel mills at a "throw-away price". Issues pertaining to the privatisation of the state-owned steel mills upset Shaukat Aziz, who served as the prime minister under the Musharraf administration.

What irked president Pervez Musharraf however was the controversial Missing Persons case that found Pakistan's intelligence agencies (including the FIA and the ISI) to be complicit in the forced disappearances of up to 400 people (including terror suspects and human rights activists) without due process since 2001. Under Chaudhry's leadership, the courts had increasingly started "exercising independence from the government" when it ordered the security agencies to produce the missing people in court.

When the Musharraf administration asked the judge to quit, Chaudhry refused to go. On 9 March 2007, Musharraf had no other choice but to suspend Chaudhry from his post for alleged and unspecified charges of misconduct and misuse of authority. The sacking of the head of the judiciary sparked bloody protests throughout Pakistan and "edged the country towards a constitutional crisis". The civil unrest grew with regards to the validity of the allegations as well as doubts as to whether Musharraf had the power to suspend the chief justice. It was on these grounds that Chaudhry waged a legal battle in the Supreme Court seeking his reinstatement. He called his suspension a "thinly veiled assault on the independence of judiciary in Pakistan".

Nationwide protests and media ban On 5 May 2007, in showing solidarity with the former chief justice, a motorcade of Chaudhry's supporters rode with him from Islamabad to Lahore where he was expected to speak at the Lahore High Court Bar Association when this motorcade of over 2,000 vehicles was stopped by the police with baton charges and tear gas shelling. Debates concerning the day's events started being covered and discussed on the Pakistani news media.

The government wanted to limit the media coverage of Chaudhry's rallies and asked the Supreme Court to warn news networks that any "media coverage, discussion and analysis" that impeded legal procedures would be treated as contempt of court. The court issued a statement in which it said the news media, particularly Geo TV host Kamran Khan, had broadcast "sensational reporting aimed at scandalising and maligning the honourable judges of the Supreme Court". Khan defended his actions by saying he had no malicious intent. But when discussions of the Chaudhry's rallies persisted on television, the government decided to take drastic measures and abruptly pulled Geo TV and Aaj TV off air.

It wasn't until 9 May 2007 that the Pakistani government imposed a complete ban on the media from discussing the suspension of Chaudhry by Musharraf. Media outlets and journalists protested and responded to the ban saying that their goal was to cover, not contribute, to the controversy. The government, reluctantly, agreed to issue special passes for reporters and lawyers to attend the presidential reference filed against the chief justice. Several pro-government parties throughout Pakistan announced their own demonstrations to coincide with Chaudhry's rallies.

Chaudhry's visit to Lahore High Court

In anticipation of the former chief justice's arrival in Lahore, the Lahore High Court was thronged by political activists of several political parties in the opposition including Pakistan Peoples Party (PPP), Pakistan Muslim League (N) (PML-N), Muttahida Majlis-e-Amal (MMA) and Pakistan Tehreek-e-Insaf (PTI), who had gathered to welcome the judge. When Chaudhry did arrive at the Lahore High Court, his motorcade was swamped by supporters showering his vehicle with rose petals and chanting "Go Musharraf, Go!" Banners denouncing Musharraf were hung all around the compound.

In his historical speech on 6 May 2007, the former chief justice made no direct references to president Musharraf but directed his rhetoric towards the government by calling it a "dictatorship". Several political commentators refer to this speech as the precursor to the Lawyers' Movement later that year. Chaudhry also accused the government of violating the basic human rights of its citizens and warned that the countries and nations that don't learn from past mistakes were bound to be destroyed. In closing his speech, Chaudhry announced he would be attending a Sindh High Court Bar Association meeting in Karachi on 12 May 2007.

Opposition plans to welcome Chaudhry After Chaudhry announced his plans for Karachi, the political parties in the opposition announced a rally to welcome the former chief justice in their city. Upon seeing Chaudhry's supporters announce a rally to welcome the chief justice, the pro-government Muttahida Qaumi Movement (MQM) organised a protest demonstration of their own against the "politicisation of the issue [of the justice's suspension]".

Seeing the chief justice's determination to visit Karachi, MQM MNA Nawab Mirza proclaimed in a parliamentary session that "no one [would] be allowed to do anything in Karachi." He said that "[the] country [may belong] to everyone, but Karachi [belonged] to [the MQM]". The provincial government called a meeting of the senior officials and instructed them to not let the chief justice leave the airport at any cost. Sindh chief secretary Shakil Durrani learnt of these plans and called them a "contempt of the High Court's orders".

On 10 May 2007, Pakistan International Human Rights Organisation filed a petition with the Sindh High Court pointing out reports in the press about Sindh home secretary Ghulam M. Muhtaram Naqvi's letter to the chief justice that requested him to postpone his visit because of intelligence reports suggesting threat of a terrorist attack. The court directed the federal and provincial governments to provide fool-proof security to the chief justice and also directed authorities not to pressurise him into changing his route while also keeping him informed of any security risks.

Unrest before Chaudhry's visit At on 10 May 2007, the residence of the Supreme Court Bar Association president Munir A. Malik came under attack by armed men. Malik, a member of the panel of lawyers defending Chaudhry, narrowly escaped the attack. On 11 May 2007, Karachi Bar Association vice president Ziauddin Sardar was reported missing by his family. Following these incidents, uncertainty and fear gripped the city as the "threat of a showdown loomed large".

Karachi Police informed it had arrested 150 people under the Maintenance of Public Order Ordinance on apprehensions they could "create problems" on the judge's arrival. However, opposition parties disputed the number of arrests – MMA put the figure at 500, PPP at 400 and PML-N at 150.

The day of the riots Fearing a showdown between rival political parties, the transporters in the city decided to keep their buses and vans off the road. In a late-night announcement, the Sindh government announced the closure of all educational institutions as governor Dr Ishrat-ul-Ibad Khan declared a public holiday for government and private schools, colleges and universities on 12 May 2007. Hospitals declared emergency and ordered their doctors and staff to remain on duty, while Naib Nazima Nasreen Jalil directed all city departments including hospitals and fire-brigade to follow "standard operating procedure" to deal with any emergency situation that arises.

City-wide blockades set up

Reports started emerging from around Karachi of blockades being set up on the way toward the Jinnah International Airport in a bid to stop the chief justice from visiting Muhammad Ali Jinnah's mausoleum. Parts of Shahrah-e-Quaideen were blocked whereas the main arterial road Shahrah-e-Faisal, which was to be used by procession of the chief justice, was completely made inaccessible.

Because most of the road leading to the airport were closed, the Pakistan International Airlines (PIA) had to delay all its flight due to the non-availability of cockpit and cabin crews who were unable to reach the airport in time. It wasn't just air traffic that was suspended but train services between Karachi and the rest of the country were also effected.

Chaudhry's arrival in Karachi At , Chaudhry left Islamabad airport on flight PK-301 for Karachi accompanied by Zamurad Khan and Yousuf Talpur. The flight landed at the Jinnah International Airport in Karachi airport at .

Gunfights broke out throughout the city as soon as the plane landed at the airport; several vehicles were also set ablaze. Smoke rose from at least four different areas of the city where competing rallies were organised.

The chief justice had plans to visit Pakistan founder Muhammad Ali Jinnah's mausoleum to address a gathering and then to the Sindh High Court to address lawyers at the 50th anniversary of the Sindh High Court Bar Association. Due to the sudden violence that erupted throughout the city, the chief justice was unable to leave the airport.
