Pakistan's Defence Minister Khawaja Asif on Wednesday said the government is mulling a possible ban on Imran Khan's Pakistan Tehreek-e-Insaf party following the attacks by his supporters on military installations after the former prime minister's arrest.

Former prime minister Imran Khan got a major relief on Tuesday when an anti-terrorism court in Pakistan granted him bail till June 8 in eight cases related to violence that erupted at the Judicial Complex in Islamabad in March.

A division bench comprising Justice Miangul Hassan Aurangzeb and Justice Saman Rafat Imtiaz heard the Al Qadir trust corruption case, a day after the Supreme Court termed Khan's arrest from the IHC premises on Tuesday as 'invalid and unlawful'.

Former Pakistan premier Imran Khan is set to appear before the Islamabad high court (IHC) on Friday for pre-arrest bail amid tight security as his party announced a rally on the occasion and asked followers to gather nearby the court for the leader's address.

In a major relief for Imran Khan, Pakistan's Supreme Court on Thursday declared the former prime minister's arrest "illegal" and ordered his immediate release after he was produced before a bench on its orders.

Khan was arrested on Tuesday in the case, sparking massive country-wide protests by his supporters.

Pakistan's anti-corruption watchdog on Wednesday sought a 14-day physical remand of former prime minister Imran Khan as he was produced before a special court inside a high security police facility in Islamabad for the hearing in a corruption case in which he has been arrested.

The court issued its reserved ruling, upsetting the Pakistan Tehreek-e-Insaf (PTI), which claimed the arrest was illegal and that the IHC would rule in favour of party chief Imran Khan.

After hearing the case, the chief justice reserved the judgment without giving a date for its announcement.

Pakistan's Interior Minister Rana Sanaullah on Tuesday said that former prime minister Imran Khan was arrested for causing loss to the national treasury in a corruption case.

Pakistan Foreign Minister Bilawal Bhutto-Zardari on Friday said his visit to Goa was a 'success' as he advocated his country's case on the soil of India.

It would be the highest level visit to India by any Pakistani leader in recent years and a possible opportunity to break the ice between the two nations.

The SHO said that Section 7 of the Anti-Terrorism Act had been included in the FIR, adding that the Chinese national would be presented before a court in Abbottabad.

Pakistan has responded to a letter by India asking to start negotiations for the review of the Indus Water Treaty, the foreign office said on Wednesday.

Pakistan, the closest ally of China, has decided to skip the Democracy Summit that begins in Washington on Tuesday, opting instead to engage with the US bilaterally to strengthen democratic values, the foreign office in Islamabad said.

A Pakistani judge on Saturday cancelled former premier Imran Khan's arrest warrants in the Toshakhana corruption case and allowed him to go home without indicting him, amidst clashes between his supporters and police outside the court complex in Islamabad.

A Pakistani court on Tuesday issued a non-bailable arrest warrant against former prime minister Imran Khan in the Toshakhana case but he was granted bail in three other cases, amid high drama outside the court premises where thousands of his supporters converged to support their leader.

'You must have heard that Pakistan is going bankrupt or that a default or meltdown is taking place. It (default) has already taken place. We are living in a bankrupt country,' Defence minister Khawaja Asif said.

Pakistan Tehreek-e-Insaf activists staged a protest after Khan was disqualified by the Election Commission of Pakistan in the prohibited funding case last year.
