Taliban militants stormed the airport complex in Afghanistan's southern Kandahar city Tuesday, triggering gunfights and explosions as a regional conference kicked off in Pakistan with hopes of reviving peace talks with the insurgents. There was no immediate information on casualties in the ongoing attack, the first major assault after days of fevered speculation that Taliban leader Mullah Akhtar Mansour was killed in an internal firefight. "Several insurgents managed to breach the first gate of the complex," Samim Khpalwak, a spokesman for the Kandahar provincial governor, told AFP.
