Afghan officials say a suicide car bombing in the southern Helmand province has targeted a police compound, killing one policeman and wounding two.

Omar Zwak, spokesman for the provincial governor, says the attack targeted a border police compound in Lashkar Gah, the provincial capital, on Friday.

Abdul Ghafar Safi, the Helmand chief of police, says there was only one bomber involved. No group immediately claimed responsibility for the attack.

Helmand is the heartland of the Taliban.

In western Farah province, spokesman Mohammad Naser Mehri says an Afghan airstrike hit a Taliban gathering, killing eight insurgents and wounding 11, as well as four civilians.

Mehri says the strike took place in the district of Khaki Safed on Thursday.
