[1/2] A supporter of former Pakistani Prime Minister Imran Khan, walks with a riot shield used by the police, during a clash outside the federal judicial complex in Islamabad, Pakistan March 18, 2023.
"Around 285 PTI supporters have been arrested in Lahore and Islamabad.
Khan, a former cricket star, was prime minister from 2018 until 2022, when he was ousted from office in a parliamentary vote.
His successor as prime minister, Shehbaz Sharif, has rejected his demand and said an election would be held as scheduled later this year.
Clashes between Khan's supporters and the security forces have brought a new round of political chaos to Pakistan, which is in the midst of a crippling economic crisis.
