A suicide bomb attack at a mosque near the town of Jamrud in the northwest Pakistani town of Jamrud has killed at least 48 people, with the death toll expected to rise. Jamrud, in the Khyber tribal agency, is in an area where Pakistani Taliban have been especially active, targeting Pakistani security forces who are protecting convoys bringing supplies to Nato troops in Afghanistan. Jamrud has also been the scene of sectarian violence between Sunni and Shia Muslims. No one has yet claimed responsibility for the attack.
