Afghanistan's Interior Ministry says a suspected suicide bomber has tried to kill the governor of southern Helmand province by detonating a car bomb outside his office.

A ministry spokesman says the blast occurred Monday just before key local officials were to meet at the governor's office.

The governor was not hurt in the explosion but the bomber, who was described as a foreigner, was seriously wounded. He later died in a local hospital.

A man claiming to be a Taleban spokesman said the attacker was a local Taleban activist.

The ousted Taleban regime and its supporters have recently stepped up insurgent activities mainly in southern and eastern Afghanistan.
