At least nine people including five Australian tourists are missing after a Malaysian boat ferrying them to an island off Borneo capsized, police said on Tuesday.
"The boat was ferrying five foreign tourists and the other four are the local staff of the tour company," a local police official in Sandakan, in Sabah state on Borneo island said.
The official said rescue operations begun in rough weather conditions.
"We have begun a search but it is raining and the sea is rough," he said.
Elsa Suliah, a official with local tour operator the Wildlife Expedition, said the Australians were heading to the nearby Libaran island when the boat capsized.
"They were heading to Libaran island. It is a 30-minute journey. They were in a medium size boat. The incident happened this afternoon," she said.
