Eleven people including three policemen were killed on Saturday in a clash between police and criminals involved in kidnapping and robberies in northwest Pakistan, police said.
The gunbattle took place in Shiekhan village 10 kilometres (six miles) southwest of Peshawar when police raided a suspected criminals' hideout, senior police officer Sher Akbar told AFP.
"We had reports that criminals involved in cases of robbery and kidnapping for ransom were hiding in the area," he said adding that the police raid triggered a shoot-out in which "eight criminals were killed."
Three policemen also died in the firefight, he said.
Doctor Jamil Shah of a local hospital confirmed the death toll.
Criminal gangs, some of whom are connected to Islamist militant networks, are active in North West Frontier Province which adjoins the restive tribal belt where Pakistan troops are fighting Taliban and Al-Qaeda linked militants.
Nuclear-armed Pakistan is on the frontline of the US war on Al-Qaeda. Washington calls the rugged tribal region the most dangerous place on Earth.
