Bangkok, Nov 4 (IANS): A tour boat capsized and sank near Thailand's popular seaside town of Pattaya Sunday, killing six people, including one Chinese and two Russians, Xinhua reported.

The double-decker ferry, en route on a 30-minute trip from Koh Lan island to Pattaya Sunday evening, carried about 200 Thai and foreign passengers, above its 130-150 capacity, the Bangkok Post reported.

Shortly after the boat departed, a technical problem occurred and caused water leakage. Many passengers on the lower deck rushed to the second floor, causing the boat to flip on one side and eventually sink.

The victims also include three Thais. At least 26 people were injured, the Nation reported.
