One passenger was killed and 30 others injured in an accident involving a tour bus, a van and a pickup truck on a mountain road in Nadi district in Thailand's Prachin Buri province yesterday. Captain Ponkhan Rattananet of Wang Khon Daeng police station said the accident occurred at about 1.50am at a curve on Highway 304. Survivors said the double-decker bus, travelling between Ubon Ratchathani and Pattaya, lost its brakes while going down a 45-degree slope and rammed into a van and a pickup truck travelling in front. The bus overturned and nearly plunged into a ravine. The van also overturned, while the truck skidded onto one side of the road. A 12km section of Highway 304, which runs over a mountain through the Thap Lan and Khao Yai national parks, is prone to accidents, with many casualties every year.
