In the Khmer Republic, government forces trying to re-open Highway Four, the main route to the capital of Phnom Penh from the main seaport of Kompong Som, have run into heavy opposition.

The Communist forces have cut the highway for a stretch of about one and a half miles (2 kms) about twenty miles (32 kms) from the capital.

The Communists are concentrating their attacks on the comparatively dry Highway Four approach to the capital as the country's monsoon waters reach their peak around Phnom Penh and are also attacking the country's third largest city of Kompong Cham, which they want to sue as a rival capital.
