Eleven insurgents have been killed in military operations in eastern Afghan provinces within the last 24 hours, said the NATO-led International Security Assistance Force ( ISAF) on Friday morning.

"Afghan National Security and Coalition Forces killed 11 insurgents, detained three suspected insurgents, discovered one weapons cache and found and safely cleared seven 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 operations were conducted in Ghazni, Laghman, Nangarhar, Paktika 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.

On Thursday morning, six US personnel and nine Afghan civilians were killed and more than 30 civilians wounded when a suicide car bombing hit a two-vehicle convoy with the coalition in a residential area in Afghan capital Kabul.

More than 10 houses were severely damaged and several civilian vehicles were destroyed in the attack which claimed by Hizb-e- Islami, the second militant group after Taliban.
