Up to 25 Taliban militants have been killed in different Afghan provinces within the past 24 hours, authorities said on Tuesday.

"Afghan police, army and the NATO-led coalition forces launched 10 joint cleanup operations in Kabul, Nangarhar, Laghman, Uruzgan, Kandahar, Wardak, Logar, Ghazni, Khost and Helmand provinces, killing 14 armed Taliban insurgents and detaining 30 others over the past 24 hours," the Afghan Interior Ministry said in a statement presenting daily operational updates.

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

Separately, up to 11 Taliban were killed in a blast in southern Kandahar province overnight, the provincial government said in a statement on Tuesday morning.

"A powerful blast took place in a weapon and ammunition reserve, killing 11 militants on the spot in the Kanjoso area of Spin Boldak district bordering Pakistan late Monday night," the statement said, adding that two local Taliban commanders were among the dead.

The Taliban insurgents, who have been waging an insurgency of more than one decade, have yet to make comments.

The Afghan forces and some 100,000 coalition troops have intensified cleanup operations against Taliban and other militants but the insurgents in retaliation responded by suicide attacks and roadside bombings.

A total of 14 people, including three NATO-led coalition soldiers, were killed and more than 50 others injured by a Taliban suicide bomber in eastern Khost province Monday morning.
