Police said Saturday they have arrested 57 renegade tribesmen in connection with recent bomb and rocket attacks that have killed several people in southwestern Pakistan.

The suspects were captured during the past 24 hours and were being questioned, senior police investigator Mujeebur Rahman said at a news conference in Quetta.

He said most detainees belonged to the Marri and Bugti tribes, whose top leaders have been accused by authorities of targeting security forces, government officials and the country's key gas installations.
