At least 12 people were killed and 59 others injured Saturday in two suicide attacks in central Afghanistan, dpa reported according to officials.
"A suicide attacker blew his explosive vest at the gate of Sayedabad district building in Wardak province and subsequently his colleague detonated his explosive-filled truck," the provincial office said.
"Eight civilians including a woman with four police officers were killed in the incidents, while 47 civilians, seven police and three intelligence officers were injured," it, adding that two soldiers with the NATO-led military coalition were also wounded.
The attack occurred near a military base. The international coalition force confirmed the attack but denied having sustained any casualties. "No NATO fatalities or injuries have been reported despite the incident happened close to the military base in Sayedabad district," Major Adam Wojack told dpa.
Taliban militants claimed responsibility for the attacks, saying their fighters targeted a US military base in the district.
"The first bomber detonated himself at the gate of the US base opening way for the truck bomber," rebel spokesman Zabihullah Mujahed said in a text message.
He said dozens of US troops were killed and scores more injured.
The civilian death toll has increased this year in Afghanistan, according to a United Nations report.
It said at least 1,145 civilians have been killed and 1,954 injured in the first six months of 2012, it said, blaming the insurgents for 80 per cent of the deaths.
