KABUL, Jan. 25 (Xinhua) -- One attacker was killed and two civilians were wounded after a suicide truck bomb rocked Afghan capital of Kabul early Sunday morning, police said.

"A truck packed with explosive was detonated along ring road in Qasaba locality at 05:45 a.m. (local time), and the explosion injured slightly two civilian passersby," the Kabul police said in a statement.

The attacker was killed on the spot and the truck was destroyed, the statement said, adding that "the explosives were planted under the fruit boxes for carrying out a subversive attack."

The potential target remained unknown but, witnesses said the target might have been the nearby front gate of military airport, lying in north of Hamid Karzai International Airport.

The road was not busy when the incident occurred.

The Taliban insurgent group claimed responsibility for the attack.

About 10,000 civilians were killed and injured in Taliban-led insurgency and conflicts in the central Asian country in 2014, according to UN mission officials.

The officials blamed the attacks of Taliban insurgents and other armed groups for most of the civilian deaths and injuries.
