Policeman among three killed in Dera Ismail Khan suicide blast: 24 nabbed as search operation launched

A suicide bomber set off a device in Dera Ismail Khan on Monday killing himself, a policeman and a passer-by after police stopped him at a checkpoint, a doctor and security officials said. The blast - the third suicide attack in Pakistan since Friday - came as police across the country were on high alert for sectarian attacks during Ashura this week.
"The attacker refused to be checked and detonated his explosives," said Aslam Khattak, a senior police official in DI Khan. Seven people, including two police personnel were wounded, he said. The dead and injured persons have been shifted to District Headquarters Hospital where emergency has been declared.
A doctor at the town's main hospital said three people had been killed, including the bomber. Security officials in Dera Ismail Khan said earlier six people had been arrested on suspicion of planning suicide attacks in late Sunday raids and some explosives seized from the suspects.
Interior Minister Aftab Ahmed Khan Sherpao said on Monday investigators were still trying to determine who was behind the attacks. Police in Sindh province said they believed suicide bombers would try to attack Shia leaders in Karachi during Muharram processions on Tuesday.

The police are investigating into the matter while security alert has been tightened all over Dera Ismail Khan.
