PHNOM PENH, Cambodia (AP) — Cambodia says its troops exchanged fire with Thai security forces along their border in their first publicly acknowledged clash since repeated combat there ended a year ago.

The deputy military commander of Cambodia’s Preah Vihear province, Lt. Col. Men Ly, says Cambodian troops on patrol Sunday were attacked by Thai forces. He says one Cambodian soldier was wounded in a 10-minute exchange of rifle fire and grenades.

Thai Army spokesman Col. Sansern Kaewkamnerd says Thai security forces inside Thai territory returned fire after illegal loggers from Cambodia shot at them and fled.

Seventeen soldiers and a civilian died in skirmishes early last year related to conflicting claims over border territory, but Thailand has also complained about cross-border log poaching.
