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.
