Fourteen militants have been killed in operations in eastern Afghanistan, said the NATO-led International Security Assistance Force (ISAF) on Saturday.

"Afghan National Security and Coalition Forces killed 14 enemies of Afghanistan, detained three suspected enemies of Afghanistan, discovered one weapons cache and found and safely cleared four 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 launched in eastern Ghazni, Khost, Paktika, Pawran and Wardak provinces, the release noted, saying nine of the militants were killed in Paktika province.

In a separate development, up to 18 Taliban militants were killed and 11 others wounded when militants launched attacks against Afghan Local Police checkpoints in Qala-i-Zal district in the country's northern province of Kunduz overnight.

Two ALP or community police members had also been killed, a provincial police spokesman Sayed Sarwar Husseini told Xinhua on Saturday.

The Taliban has intensified attacks since late April when they launched annual rebel offensive against Afghan and about 100,000 NATO-led forces stationed in the country.

The militant group has yet to make comments.
