QUETTA: Clashes erupted once again between the border forces of Afghanistan and Pakistan near the key Chaman-Spin Boldak border crossing on Thursday, resulting in one death and over a dozen injuries, Pakistani officials said.

Previously, cross-border shelling and gunfire killed eight Pakistani civilians and one Afghan soldier on Sunday near the same crossing, which connects Pakistan’s southwestern province of Balochistan with the southern Afghan province of Kandahar.

Thursday’s fighting started when Pakistani forces repairing a portion of the border fence damaged during Sunday’s clashes came under attack from the Afghan side of the frontier, a provincial official Balochistan, Zahid Saleem, told Reuters.

The police spokesman of the Afghan province of Kandahar did not immediately reply to a Reuters request for comment on the fresh fighting. Both sides blamed each other for instigating Sunday’s clashes.

Saleem, who is additional chief secretary of the province, said Afghan mortar shells had landed in civilian settlements on the Pakistani side.

“One civilian has been killed and 12 others, including women and children, were injured,” a local official of the Pakistani border area of Chaman said, adding that clashes were still ongoing.

Afghanistan and Pakistan have for decades had territorial disputes at their border and the Chaman crossing was closed for several days after similar clashes last month.

Chaman-Spin Boldak is the second busiest crossing between the two countries and a key trade route through which large quantities of critical goods move in and out of landlocked Afghanistan.
