ISLAMABAD — Pakistani security forces launched an operation Tuesday night to disperse supporters of imprisoned former Prime Minister Imran Khan who had gathered in the capital to demand his release from prison.
The latest development came hours after thousands of Khan supporters, defying government warnings, broke through a barrier of shipping containers blocking off Islamabad and entered a high-security zone, where they clashed with security forces, facing tear gas shelling, mass detentions and gunfire.
Tension has been high in Islamabad since Sunday when supporters of the former prime minister began a ''long march'' from the restive northwest to demand his release. Khan has been in a prison for over a year and faces more than 150 criminal cases that his party says are politically motivated.
Khan's wife, Bushra Bibi, led the protest, but she fled as police pushed back against demonstrators. Hundreds of Khan's supporters are being arrested in the ongoing nighttime operation, and police are also seeking to arrest Bibi.
Interior Minister Mohsin Naqvi told reporters that the Red Zone, which houses government buildings and embassies, and the surrounding areas have been cleared. Leaders from Khan's Pakistan Tehreek-e-Insaf party, or PTI, have also fled the protest site.
Earlier Tuesday, Pakistan's army took control of D-Chowk, a large square in the Red Zone, where visiting Belarusian President Alexander Lukashenko is staying.
Since Monday, Naqvi had threatened that security forces would use live fire if protesters fired weapons at them. ''We have now authorized the police to respond as necessary,'' Naqvi said Tuesday while visiting the square.
Before the operation began, protester Shahzor Ali said people had taken to the streets because Khan had called for them. ''We will stay here until Khan joins us. He will decide what to do next,'' Ali said.
