A suicide bomber rammed his explosive-laden car into a police check post in northwestern Pakistan's troubled Swat valley on Sunday, killing at least 9 people, the army spokesman Major General Waheed Arshad said.
Arshad was quoted by local TV channels as saying that three policemen were among those killed and at least seven others were injured as a result of the attack in Swat valley in North West Frontier Province.
No group has claimed responsibility for the blast, but Arshad termed the incident as terrorist attack and carried out by the militants.
The security forces on Sunday vowed to catch militants' leader Maulana Fazlullah, who had reportedly fled to the northwestern part of Swat valley.
Fazlullah said through his FM radio that he still had enough number of followers to fight the security forces for a long time. He also disclosed that he had prepared suicide bombers for security forces.
The army said Saturday that it had controlled most of Swat valley and the militants were on the run. It also confirmed that up to 290 militants were killed and 143 others were arrested in the operation.
Major General Nasser Janjua said that the operation was expected to end in three to four months in the area. However, he also mentioned that the militants remained dangerous and would likely try to regroup for at least one major counter-attack.
