Deadly blasts hit Pakistani city

At least 11 people have been killed and hundreds of others injured in three blasts in Peshawar, the capital of Pakistan's North West Frontier Province.A fourth bomb blast hit a hospital in Dera Ismail Khan, which lies 300km south of Peshawar, but there were no immediate reports of casualties.Thursday's attacks began when two bombs exploded in a market in Peshawar, killing six people. Armed men on rooftops fired at policemen as they arrived in the narrow lanes below.  Shortly after, a suicide bomber attacked a checkpoint on the outskirts of the city, killing five soldiers, Wasiullah, a soldier wounded in the blast, said."He was on foot and as we saw him, he ran and blew himself when he got close to us," he told the Reuters news agency.Al Jazeera's Mike Hanna, reporting from Islamabad, said it appeared the series of bomb blasts were "inextricably linked"."Certainly that is the way Pakistan's intelligence services are seeing it - investigating this wave of bombings that is happening in recent days," he said.Police later said that two assailants from the market bombings had been killed and two suspects detained."Two terrorists have been killed but the operation is continuing. We're carrying out searches as others could be hiding," Sifwat Ghayyur, Peshawar's police chief, said.
