Officials in Afghanistan's Helmand province say suicide bombers have attacked a bank in the provincial capital, Lashkar Gah.
A spokesman for the governor of the southern province said two men wearing explosive vests entered the Kabul Bank branch on December 17 and that one of them detonated his explosives.
He said there were casualties but it was unclear how many.
Farid Ahmad Obaid, a spokesman for Helmand's police chief, said police believe "there were four Taliban, one of them detonated his explosives and three are fighting with security forces."
Witnesses said that a blast and gunfire were heard, and that the attack was continuing.
Employees who escaped said the attack occured as several government workers were in the bank to collect their salaries.
