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.

Frantic escape by party leaders during a security crackdown could hurt the PTI. But the government faces questions too.

Islamabad Police Inspector General Ali Nasir Rizvi confirmed that 954 individuals had been arrested between Sunday and Tuesday, as protesters came within 1.6 kilometers of their intended target. The government reported at least one police officer and four paramilitary personnel were killed during the clashes.
