A truck driver and his wife were killed when a B40 rocket-propelled grenade

attack hit their vehicle on Route 4 between Phnom Penh and Sihanoukville on July

5.

The attack happened just west of the Preah Suramarit-Kossomak National

Park, about 100km southwest of Phnom Penh.

A spokesman for the Doung

Chhiv Import-Export & Transporation Co, which owns the container truck, said

villagers said three Khmer Rouge guerrillas had attempted to stop the

vehicle.

When the driver did not stop, one of the KR fired the

grenade.

KR radio has claimed responsibility for the attack, which

follows the killing of one person and wounding of three others near Route 4 by

guerrillas last month
