An explosion in southern Afghanistan on Tuesday morning killed at least two people and injured dozens, officials said.
A truck exploded while traveling through Lashkar Gah, the capital of Helmand province, en route to what officials said was its presumed target, the provincial police headquarters.
Omar Zwak, spokesman for the governor of Helmand, said in an interview that 51 people, mostly civilians, were wounded in the blast.
No group immediately claimed responsibility for the attack.
Civilian casualties in the Afghanistan conflict continue to rise in 2015. According to the United Nations Afghanistan mission, the first four months of the year saw 1,989 civilian injuries and another 978 deaths, greater than in the same period in 2014.
