PHNOM PENH (AP)-Raiders from Cambodia recently crossed the border and killed four

Vietnamese, wounded two and raped two others, a UNTAC spokesman said Nov. 26.

In addition, the wife, son and two daughters of a Cambodian politician were seriously

injured on Nov. 23 in a grenade attack on his home in Svay Rieng, 115 kilometers

east of Phnom Penh, spokesman Eric Falt said.

The politician, a member of FUNCINPEC, was not home at the time, Falt added.

He said local police were investigating the incident under the supervision of UNTAC

civilian police.

"We are extremely bothered by reports of there further attacks despite our calls

for restraint," said Dennis McNamara, head of UNTAC's human rights component

in Cambodia.

He and the UNTAC Chief Yasushi Akashi, both urged Cambodia's four factions last week

to put an end to a recent upsurge in racist and political attacks.

But skirmishes in the countrside, as well as political and racist attacks, have hamperd

the U.N. operation. Since early November, U.N. officials have reported six grenade

attacks on opposition politicians, their families or their property.

Falt said a grenade had recently been found and safely detonated at a voter registration

site but he did not know which one.

Although U.N. officials have not assigned blame for the attacks, McNamara implied

that the Phnom Penh regime might be responsible for some of them.
