Pakistani forces clashed on Thursday with hundreds of Afghans stranded on Pakistan’s side of a commercially vital border crossing with Afghanistan after its closure by Taliban insurgents, Pakistani security officials said.

The disturbances broke out after a 56-year-old Afghan traveller died of a heart attack as he waited in the dusty heat to enter Afghanistan via the Chaman-Spin Boldak crossing, Arif Kakar, a Pakistani official on the scene, said.

Protesters carried his body to a local Pakistani government office demanding the border be reopened. Some began throwing stones at security forces, who responded by firing tear gas and charging the protesters with batons to disperse them. No injuries were reported.

The Chaman-Spin Boldak crossing is landlocked Afghanistan’s second busiest entry point and main commercial artery to the Pakistani seacoast.
