ISLAMABAD (REUTERS) - The Pakistani Taleban spokesman announced a one-month ceasefire on Saturday aimed at reviving failed peace talks with the government.

"The senior leadership of the Taleban advises all subgroups to respect the Taleban's call for a ceasefire and abide by it and completely refrain from all jihadi activities in this time period," the statement said.

The unilateral ceasefire comes after attempts to hold peace talks between the militants and government collapsed. In recent weeks the Pakistan air force has bombed militant targets in the the northwest, and there is speculation that the army will launch an offensive in North Waziristan, a tribal region bordering Afghanistan.
