Thousands of supporters of Pakistan's jailed former Prime Minister Imran Khan marched on the capital Islamabad this week, breaking through barricades and clashing with police in response to his call for a sit-in protest.

At least six people have died in protest-related violence as supporters seeking Imran Khan’s release from prison broke through barriers meant to lock down Islamabad.

Supporters of the ex-prime minister marched toward Islamabad, the capital. Clashes with the police left at least one officer dead, the authorities said.
