Afghan security forces have killed seven militants in the latest military operation in Logar Province, where Taliban insurgents have a strong presence, a local police chief has said.

Esmatullah Alizai said that government forces also seized weapons from the militants during the operation in Logar's volatile Charkh district on March 24.

Alizai said more than 20 militants were killed, 10 wounded, and four others detained since the military sweep in Logar, southeast of the capital, Kabul, began three weeks ago, amid Afghanistan's spring fighting season.

Elsewhere in Afghanistan, officials say security forces uncovered a plot to detonate explosives inside a mosque in the northern province of Sar-e Pol.

Provincial Governor Mohammad Zahir Wahdat said on March 25 that a man was arrested in suspicion of planting a bomb inside the Guzar Shahan mosque ahead of Friday Prayers on March 24.
