In Pakistan, at least 50 people have been killed in a bombing in a crowded area of the north-western city of Peshawar. More than 100 people have also been injured in the suspected suicide bombing. Doctors at the Lady Reading hospital, close to the blast site, warned that the toll could rise as many of the injured were in a critical condition. Officials said a vehicle laden with explosives had been detonated near the city's Khyber Bazaar. The bomber used at least 50kg of explosives, laced with bearings and shells to cause maximum damage in a crowded civilian location. TV footage showed what appeared to be the charred frame of a bus destroyed by the explosion. Many of the victims of the blast were thought to be passengers and police said this included a number of children. The remains of other vehicles were strewn in the road. Hours earlier, police said gunmen in Peshawar had attacked vehicles being used to take supplies to Nato forces in Afghanistan, setting them on fire and destroying them.
