Opposition supporters in Pakistan have temporarily called off protests demanding the release of jailed former prime minister Imran Khan, a day after marching on central Islamabad. Protesters had vowed not to leave the capital until Khan's release.

Pakistani security forces pushed a protester off a 25-foot tall stack of shipping containers as they were accused of opening fire on supporters of Imran Khan at a huge demonstration in Islamabad.

The party of Pakistan's jailed former Prime Minister Imran Khan suspended street protests seeking his release, it said on Wednesday, following media reports of hundreds of arrests by security forces in a sweeping midnight raid in the capital.
