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. A purported spokesman for the Taleban said the group was behind the attack.
