A twin suicide bombing targeting a Nato base in eastern Afghanistan has killed eight civilians and four Afghan policemen.
A spokesman for Nato's International Security Assistance Force (Isaf) said no one from the alliance was killed but two soldiers were wounded in the attack in Wardak province's Sayed Abad district.
The Taliban, which took responsibility for the Saturday morning attack, said it had dispatched two suicide bombers, one travelling on foot and another in an explosives-laden truck.
Government officials said the first attacker blew himself up to try to eliminate the Afghan security force guarding the compound and clear the way for the truck to hit the base down the road from the governor's complex.
The second bomber then blew up the fuel tanker as he was approaching the base.
Sahidullah Shahid, spokesman for the provincial governor, said: "The truck bomb was huge, killing 12 and wounding 50 more."
The Nato base was targeted last year on the eve of the tenth anniversary of the September 11 attacks, when a suicide bomber drove into it, killing four civilians and wounding 77 US troops.
Wardak province saw the worst single incident suffered by foreign forces in over 10 years of war when the Taliban shot down a transport helicopter last year, killing 38 troops, 30 of whom were American, mostly elite Navy SEALs.
Two US troops were also killed on Saturday in a separate insurgent attack in eastern Ghazni province, Isaf said in a statement.
Violence has increased across Afghanistan as the 2014 deadline for Nato to withdraw most of its troops approaches, and fears are mounting that the 350,000-strong Nato-trained Afghan security forces will not be able to tackle insurgents once they leave.
