Eleven Taliban militants have been killed, five wounded and eight others arrested in military operations in different Afghan provinces within the last 24 hours, the country's Interior Ministry said Tuesday morning.

"Afghan National Police (ANP) supported by the army, intelligence agency and the NATO-led coalition forces conducted cleanup operations in Nangarhar, Parwan, Kunduz, Kandahar, Logar, Herat and Helmand provinces, killing 11 armed Taliban militants, wounding five and capturing eight other suspects over the past 24 hours," the ministry said in a statement.

The ANP also found and seized weapons, the statement said, without saying if there were any casualties on the side of security forces.

The Taliban insurgent group, which has been waging an insurgency of more than one decade, has yet to make comments.

The Afghan security forces and the NATO-led coalition troops have intensified operations against Taliban and other militant groups recently. But the insurgent groups responded by bombings.

Earlier Tuesday, three civilians were killed and one was wounded when their vehicle was hit by a Taliban Improvised Explosive Device (IED) in southern Helmand province, some 555 km south of Afghan capital Kabul.

On Monday, one civilian and a militant were killed when Taliban carried out a suicide bombing against a convoy of US Special Forces in eastern Kapisa province 65 km north of Kabul, according to local media reports, adding no member of the convoy was hurt in the bombing.

In northern Badakhshan province, two militants were killed and three policemen wounded when the militants ambushed a police convoy in Wardoj district in the province 315 km north of Kabul on Monday, the provincial police chief Imamuddin Motmahin told Xinhua.
