( dpa ) - At least two people were killed and 20 injured in a suicide attack at a security convoy in north-west Pakistan on Saturday, as the police launched a probe into the bombing that left 42 people dead during the funeral on Friday, officials said.
The suicide bomber rammed his explosives-laden vehicle into two paramilitary vehicles travelling near Khar, the main town in Bajaur tribal district that borders Afghanistan.
A security official was killed, while the torched body of the suicide bomber has also been recovered from the vehicle, said local government official Iqbal Khattak. Nine law enforcement officers and 11 civilians were also injured in the attack.
Pakistan's tribal areas are believed to have safe-havens of al- Qaeda militants and Taliban fighters who launch cross-border attacks on international forces into Afghanistan.
The blast came a day after a suicide attack at a Muslim funeral prayer for Javed Iqbal, a deputy police superintendent,left 42 people dead and 81 injured in Mangora, a town in restive Swat Valley of the neighbouring North-West Frontier Province. Iqbal himself had been killed Friday morning in a roadside bomb attack.
No one has claimed responsibility for the suicide attack. But local officials believe it was carried out by the followers of pro- Taliban cleric, Maulana Fazlullah, who is thought to be behind dozens of suicide bombings in the scenic valley since October 2007 when the Pakistani Army was sent to the area to flush out Islamic militants.
"The security forces have cleared much of the area of the insurgents but some of them are still hiding in the mountains from where they conduct such heinous actions," district police officer Waqif Khan said.
Hundreds of mourners were assembled in Mangora town on Saturday morning to attend the joint funeral for several of the victims.
"Last night 37 bodies and 86 injured were moved to the hospital. Five succumbed to injuries later in the night," said Mohammed Khan, medical superintendent at Saido Sharif hospital.
Friday's suicide attack was the latest in a series of bombings Pakistan has seen since July 10, 2007 when army commandos stormed the so-called Red Mosque in Islamabad to end a siege by armed militants. Hundreds of people were believed to have died in the army attack.
Since then the militants have targeted the security forces in well-organized attacks, which also include more than half around the military headquarter in the garrison city of Rawalpindi. Around 1,000 people have died in the militant attacks in last 13 months.
