Up to seven insurgents have been killed and eight others detained in military operations in eastern Afghan region in a 24-hour time, the NATO-led International Security Assistance Force (ISAF) said Tuesday.

"Afghan and coalition forces killed seven insurgents, detained eight, and cleared one improvised explosive device (IED) during operations in eastern Afghanistan throughout the past 24 hours," the ISAF's Regional Command-East (RC-East) said in a statement.

Afghan Border Police killed seven insurgents during an engagement in Barge-E Matal district, Nuristan province 180 km east of Kabul, it said.

The captured insurgents were arrested in Ghazni and Logar provinces. The detained suspects were transferred to military bases for questioning, it added.

Operations in RC-East are still ongoing.

The Afghan and NATO military officials use the word insurgents referring to Taliban insurgents.

However, the Taliban insurgent group, which launched an annual spring offensive from May 3 against Afghan and some 100,000 NATO forces, has not yet to make comments.
