ISLAMABAD, 18 August 2007 — At least 22 people — seven soldiers and 15 militants — were killed in clashes in Pakistan’s tribal region of South Waziristan yesterday, local TV channels reported.

Several others from both sides were also injured in the fighting between security forces and militants in the troubled region. There has been no official confirmation about the clashes.

In a separate incident, a suicide attacker rammed his explosive-laden vehicle into a military convoy in troubled northwestern Pakistan yesterday, wounding at least five soldiers in the blast, police said.

Troops killed two foreign militants in fighting in another area in the northwest, an official said.

The soldiers were traveling through the town of Tank, 50 kilometers (30 miles) west of the city of Dera Ismail Khan in the South Waziristan region, when the attacker struck, said Idrees Khan, an area police chief.

He said the injured soldiers had been transported to a hospital, and body parts of the bomber were being collected.

At Mir Ali, in North Waziristan, militants opened fire on troops near a checkpoint, said a local security official on the condition of anonymity because he was not authorized to speak to media. Two foreign militants, including one who appeared to be an Uzbek, were killed and two others were captured, the official said.
