ISLAMABAD, Pakistan (CNN) -- A rocket attack killed at least 11 people and injured 30 others on Thursday evening in northwest Pakistan, a Khyber Agency official said.
Unknown militants fired four rockets near the town Landi Kotal, hitting a warehouse near a market and a base for the Pakistani Frontier Corps, a paramilitary organization that operates in the frontier region and tribal areas.
Khyber Agency is one of seven semi-autonomous tribal agencies along the Afghan border.
Workers on Friday continued to clear rubble from the attack, with the possibility that the death toll could rise.
