Kabul - Unknown gunmen

Kabul  - A suicide bomber rammed his explosive-laden vehicle into a convoy of NATO-led forces in western Afghanistan on Saturday, wounding four soldiers, officials said Saturday.

The bomber attacked Italian troops near an airport on the outskirts of the capital of Herat province, regional police spokesman Abdul Raouf Ahmadi said.

"The bomber died in the attack, and one of the Italian military tanks was thrown out of the main road, because the blast was very powerful," Ahmadi said.

Kabul -  Gunmen killed a tribal elder and his son in an attack in southern Afghanistan, while elsewhere at least 22 insurgents were killed and eight others were detained in separate operations by Afghan and international forces, officials said Saturday.
