A top leader of Pakistan's Taliban may have been killed in a clash with Afghan forces near the border, a senior Afghan police officer said on Thursday. Maulvi Fazlullah, the head of a Taliban faction in the Swat Valley, was reportedly killed along with six of his comrades in the Barg Matal district of Afghanistan's Nuristan province, which lies close to the border with Pakistan, said Mohammad Zaman Mamozai, chief of the Afghan border force for the eastern region. Our units have reported that Fazlullah has been killed. We don't yet know if it's true or not. We're investigating this right now, Zaman said. The bodies were recovered by the police, he said, adding: We're investigating to find out if Maulana's body is among those seven. We have reports from our sources that he has been killed in Bargi Matal clashes.
