Horror for onlookers as plane crashes into the sea

At least five police officers have been killed after a small plane crashed into the sea in Thailand.

The plane crashed into the sea about 100metres (330ft) off shore and the wreck appears to have broken in two.

There were six police officers on board the plane when it crashed, Royal Thai Police said.
