KUALA LUMPUR, Malaysia — Gunmen ambushed and killed six Malaysian police officers as fears mounted that armed intruders from the southern Philippines had slipped into at least three coastal districts on Borneo island, officials said Sunday.
Six of the attackers were also fatally shot Saturday night, while another was beaten to death by angry villagers, escalating tensions in eastern Sabah state, where Malaysia’s biggest security crisis in recent years began after about 200 members of a Philippine Muslim royal clan occupied a village last month to claim the territory as their own.
Security forces clashed with the clan members in the coastal area of Lahad Datu on Friday, leaving 12 Filipinos and two Malaysian police commandos dead.
The remaining clan members have refused to budge, while concerns have grown that other groups from the Philippines’ restive southern provinces might enter Sabah, which shares a long sea border with the Philippines that is difficult to patrol. The Malaysian and Philippine navies have strengthened their presence in waters near their border, according to Filipino officials.
A police team was attacked late Saturday while inspecting a settlement in Semporna town, more than 90 miles from Lahad Datu, said national police chief Ismail Omar.
Six of the assailants were fatally shot by police at the settlement and another was beaten to death by villagers whom he apparently tried to take captive while armed with a rifle, said Sabah police chief Hamza Taib.
Police said they were also investigating sightings of armed foreigners in military-style clothing in a third Sabah seaside district nearby. It was not clear whether the groups in the three areas had links to each other.
Prime Minister Najib Razak of Malaysia said Sunday that army reinforcements have been sent to Sabah, adding that he was confident about their ability to control the situation.
