Afghan officials say a senior adviser to President Hamid Karzai and a member of parliament have been killed during an attack in the capital, Kabul.

The officials said Jan Mohammad Khan, a former governor of southern Uruzgan province and a close adviser to Mr. Karzai, was killed along with Uruzgan lawmaker Mohammad Ashim Watanwal late Sunday when two men wearing suicide vests attacked Khan's home in western Kabul's Karte Char district.

Taliban spokesman Zabiullah Mujahid claimed responsibility for the attack, accusing Khan of helping American forces.

The attack came less than a week after the assassination of Mr. Karzai's brother, Ahmad Wali Karzai, in southern Kandahar province.

In other violence Sunday, Afghan and foreign troops killed at least 10 Taliban fighters in a school in eastern Nangarhar province. Officials said the coalition forces targeted the militants using ground troops and airstrikes. No children were in the school during the attack.

And NATO said two of its service members were killed in a bomb blast in southern Afghanistan Sunday.
