AP: Pakistani security forces on Sunday carried out an intelligence-led ground operation along the Pakistan-Afghanistan border, striking militant hideouts and killing 29 fighters, officials said. Authorities said the action responded to a series of militant attacks nationwide. A day earlier, gunmen with explosives attacked the Pakistan Rangers' regional headquarters in Karachi, killing three soldiers; security forces killed three attackers and detained another, whom the military said was an injured Afghan national. A splinter faction of the Pakistan Taliban calling itself the Free Men Party claimed responsibility for the Karachi attack.(金十数据)
