Pakistani police besiege Imran Khan's home as deadline for him to hand over suspects is to expire

Pakistani police kept up their siege around the home of Imran Khan as a 24-hour deadline given to the former premier to hand over suspects allegedly sheltered inside was about to expire on Thursday.

The siege and the authorities demand for the suspects, wanted in violent protests over Khan's recent detention, has angered the former prime minister's many followers and is raising concerns about more clashes between them and the security forces.

Last week, Khan's supporters attacked public property and military installations after he was dragged out of a courtroom and arrested. At least 10 people were killed in clashes with police across the country. The violence subsided only when Pakistan’s Supreme Court ordered Khan's release.

The popular opposition leader was freed from custody over the weekend and returned to his home in an upscale district of Lahore, Pakistan’s second largest city and the capital of the Punjab region. Dozens of his supporters have been staying there with him, along with private guards. Police, who on Wednesday surrounded the residence, say they want 40 suspects handed over.

The ultimatum for Khan ends at 2 p.m. local time.

“Probably my last tweet before my next arrest,” the 70-year-old popular opposition leader tweeted on Wednesday, after the siege started. “Police have surrounded my house.”

According to Amir Mir, a spokesman for the Punjab provincial government, police were ready to use firearms if attacked. He told a news conference Thursday that at least 3,400 suspects linked to the clashes have been arrested and that more raids are planned.

Pakistani authorities have said they would prosecute civilians involved in recent anti-government protests in military courts.

The announcement has drawn criticism from the advocacy group Amnesty International and the Human Rights Commission of Pakistan, which oppose trials of civilians in the military courts. Military trials in Pakistan are usually held behind closed doors, depriving civilians of some of their basic rights, including contracting a lawyer of their choice.

Khan was ousted by a non-confidence vote in Parliament last year. He has claimed the ouster was illegal and a Western conspiracy.

He now faces more than 100 legal cases, mainly on charges of inciting people to violence, threatening officials, and defying a ban on rallies. He also faces a graft case along with his wife and was summoned by the National Accountability Bureau to answer questions in connection with the case on Thursday.

However, Khan is likely to ignore the summons from the anti-corruption authority to show up for questioning in the garrison city of Rawalpindi. He is expected to address a rally of supporters on the outskirts of Lahore later in the day.
