At least 20 people died and more than 50 others were injured when a car bomb exploded outside a bank in Lashkar Gah, capital of the southern Afghan province of Helmand on Thursday, according to Reuters.

Those, who were killed and injured in the incident, are civilians and members of the security forces waiting to collect their pay, officials said.

There was no immediate claim of responsibility but insurgent groups, including the Taliban and Islamic State have in the past targeted banks where police, soldiers and other government employees collect their pay.

Last month, at least three people were killed and many wounded in an attack on a bank in the eastern city of Gardez.
