Peshawar (Pakistan) (AFP) – A blast on a bus carrying government employees in northwest Pakistan on Friday killed at least 10 people and wounded more than 40 others, officials said.

Police said the explosion appeared to have been caused by a bomb but this has yet to be confirmed. Gas fuel cylinders sometimes cause blasts on buses in Pakistan.
