Seven insurgents have been killed in joint operations in eastern Afghan provinces, said the NATO-led International Security Assistance Force (ISAF) on Monday.

"Afghan National Security and Coalition Forces killed seven insurgents, detained four suspected insurgents, discovered two weapons caches and found and safely cleared eight improvised explosive devices during operations in eastern Afghanistan throughout the past 24 hours," the ISAF's Regional Command-East said in a press release.

The raids were conducted in Khost, Paktiya, Paktika, Nangarhar and Wardak provinces, the release added.

Afghan and ISAF officials use the term insurgents for referring to Taliban.

However, the insurgent group, which has been waging an insurgency for more than one decade, has yet to make comments.

The Afghan security forces and the ISAF troops have intensified operations against Taliban and other militant groups recently. But the insurgent responded by bombings and armed attacks.

On Sunday, up to 10 Afghan cops were killed and four wounded when Taliban launched an armed attack and a roadside bombing in eastern Ghazni and neighboring Nangarhar province.
