Two people were killed and two wounded Wednesday when a missile fired from Afghanistan landed near a border post in a Pakistani tribal area, a senior security official said. It was not clear if the missile that hit the troubled Bajaur district was launched by Taliban militants in Afghanistan or international forces fighting them, the official said. The missile apparently "fired from the eastern Afghan province of Kunar landed near a Pakistani check post" in Sakhi Pass area of the tribal district, senior security official Javed Khan told Agencies.
