A suicide bomb attack in a crowded Afghan bazaar in a remote town, 100 Kms away from Kabul has killed four civilians and injured 14, on Monday.

Four civilians were martyred and another 14 were wounded, Faizanullah Pattan, provincial governor's spokesman said, adding that he failed to assess what the attacker's target had been.

The small town of Najeel Khail in Alishing district of Laghman province, was not protected by any military patrol when the explosive strapped bomber attacked the region.

A string of suicide bombing has followed the Talibans’ announcement of the the beginning of their Spring offensive against Afghan and international forces, last month.

On Sunday, six police officers of the Afghan Security forces were killed in a suicide bombing attack on traffic police headquarters in east Afghanistan.

Another suicide bomber had killed six students at a heavily-guarded military hospital.

Al-Qaeda leader Osama bin Laden’s death in the hands of US troops has put the Afghan security forces under pressure to take over the responsibility for security in some safer areas from July, letting the foreign troops withdraw sooner than expected.
