ISLAMABAD: At least eight supporters of Pakistan Tehreek-e-Insaf (PTI) were killed and dozens of others injured in Islamabad following what the party said was a sweeping crackdown overnight by security forces to disperse protesters demanding the release of jailed former prime minister and PTI chief Imran Khan.

Imran Khan has not permitted us to move beyond D-Chowk. We will strictly follow his instructions.

Thousands of demonstrators supporting former Pakistani Prime Minister Imran Khan broke through barricades around Islamabad on Tuesday, killing four security service members and moving toward the center of the city.
