A roadside bomb attack targeted a former Pakistan provincial cabinet minister on Sunday, killing him and three other people in the country's restive northwest, police said. The bomb exploded in Bagto village, about 10 kilometres (six miles) from the northwestern town of Hangu in an area with a history of sectarian clashes between Pakistan's majority Sunni Muslims and minority Shiite Muslims. 'Four people, including Ghanni-ur Rehman (a former cabinet minister in North West Frontier Province) have died in the attack,' Hangu city police chief Abdul Rashid Khan told selfnews. 'The other three are a bodyguard, his driver and a friend,' he added. A doctor at the main hospital in Hangu confirmed Rehman and three other people were killed in the attack. 'It was a remote-controlled roadside bomb blast,' police spokesman Fazal Naeem told selfnews by telephone. Taliban and Al-Qaeda-linked militants attack daily across northwest Pakistan and the lawless tribal belt on the Afghan border that Washington has branded the most dangerous part of the world. Bagto village is close to Orakzai, home of Hakimullah Mehsud -- head of the country's main Taliban faction -- and one of the seven districts that make up the semi-autonomous tribal belt.
