Berliner Boersenzeitung - Former Pakistan PM Imran Khan arrested during court appearance

Officials from Khan's Pakistan Tehreek-e-Insaf (PTI) party urged supporters to take to the streets after his arrest but police warned that an order prohibiting gatherings of more than four people would be strictly enforced.

It was not immediately clear if Khan was being held at the Islamabad High Court, or had been moved elsewhere.

"Imran Khan has been arrested in the Qadir Trust case," the official Islamabad police Twitter account said, referring to a graft case.

Local TV stations showed chaotic scenes outside the court as hundreds of PTI supporters clashed with security officers.

Khan's arrest comes a day after the military warned him against making "baseless allegations" after he again accused a senior officer of plotting to kill him.

The rebuke late Monday underscored how far Khan's relations have deteriorated with the powerful military, which backed his rise to power in 2018 but withdrew its support ahead of a parliamentary vote of no confidence that ousted him last year.

Pakistan is deeply mired in an economic and political crisis, with Khan pressuring the struggling coalition government for early elections.

At a weekend rally in Lahore, Khan repeated claims that a senior intelligence officer Major-General Faisal Naseer was involved in an assassination attempt last year during which he was shot in the leg.

The military's Inter-Services Public Relations (ISPR) wing said in a statement that "this fabricated and malicious allegation is extremely unfortunate, deplorable and unacceptable".

"This has been a consistent pattern for the last year wherein military and intelligence agencies officials are targeted with insinuations and sensational propaganda for the furtherance of political objectives," it said.

Criticism of the military establishment is rare in Pakistan, where army chiefs hold significant influence over domestic politics and foreign policy and have long been accused of interfering inthe rise and fall of governments.

Prime Minister Shehbaz Sharif -- whom Khan also alleged was involved in the assassination plot -- weighed in on Twitter.

"His levelling of allegations without any proof against Gen Faisal Naseer and officers of our Intelligence Agency cannot be allowed and will not be tolerated," he said.

- Rejects findings -

Pakistan's government has said the assassination attempt was the work of a lone gunman, who is now in custody and who confessed in a video controversially leaked to media.

Khan rejects those findings and insists authorities have refused to accept his attempts to file a so-called first information report (FIR) with police identifying the real culprits.

Khan repeated his allegations in a video statement released ahead of his court appearance Tuesday, saying that "there is no reason for me to fabricate the facts".

ISPR said it reserved the right to "take legal course of action against patently false and malafide statements and propaganda".

Khan faces dozens of charges that were brought against him since he was ousted -- a tactic analysts say successive Pakistan governments have used to silence their opponents.

Pakistan's military, the world's sixth largest, holds undue influence over the nation.

It staged at least three coups since the country gained independence in 1947 and ruled for more than three decades.
