In Pakistan, a suicide bomber has killed five people and injured 26 others in the city of Peshawar, detonating explosives at a check post on a busy road. Senior police officer Karim Khan said the bomber was on foot and detonated explosives strapped to his body during a body-search at the check post. The check post is on the city's Mall Road, which houses offices of the national airline and some media companies. It is also close to a Christian girls' school and the city's military district. Top city official Sahibzada Anis said the dead included one policeman. Mr. Anis said the bomber had apparently been heading towards a market. The blast sparked panic in offices and shops along the road. Security is very tight in Peshawar and elsewhere across the country, with police checkposts on roads and guards at the gates of public buildings.
