LASHKAR GAH, Afghanistan, Feb. 24 (Xinhua) -- Two Afghan army soldiers were killed in a suicide car bomb blast in restive southern Helmand province on Friday, an army source in the province said.
"The explosion took place after a man detonated a car bomb near an army checkpost in Greshk district at around midday," Major Khairullah Khan told Xinhua.
One soldier was injured and the security checkpoint, locating along Kandahar-Herat highway, was also damaged in the blast, the source added.
Security forces have cordoned off the area for precautionary measures.
So far, no group has claimed responsibility for the attack, but the Taliban militant group has launched similar attacks in the past.
Helmand, notorious for poppy growing, is also a known Taliban stronghold.
