A suicide bomber has killed the governor of Afghanistan's Paktia province and two other people.
Officials in the eastern province say the governor Abdul Hakim Taniwal, his nephew and chief bodyguard died when a man carrying a bomb detonated it near the official's car in Gardez. At least three police officers were wounded.
A purported spokesman for the Taleban said the group was behind the attack.
Also Sunday, NATO officials said NATO and Afghan troops killed 94 Taleban rebels in four encounters in Kandahar province overnight.
The U.S. military, meanwhile, warns that a suicide bombing cell is operating in (the Afghan capital,) Kabul and looking for chances to target foreign troops.
On Friday, a suicide bomber rammed his car into a U.S. convoy near the U.S. Embassy and killed 16 people, mostly Afghan bystanders.
In other violence, two policemen were killed in western Farah province late Saturday when dozens of Taleban militants raided a police compound.
NATO-led troops have been conducting a major offensive in southern Afghanistan to put down an increasing insurgency by the Taleban. NATO says more than 400 insurgents have been killed during the week-long offensive.
