Pakistani security forces have been accused of opening fire on supporters of Imran Khan, the jailed former prime minister, who stormed Islamabad this week to demand his release.

Nearly 4,000 people arrested and at least seven people, including a police officer and members of security forces, lost their lives

Khan’s wife, Bushra Bibi, who was leading the protest, and other demonstrators fled in vehicles when police pushed back against the rallygoers following clashes in which at least seven people were killed.
