TAIPEI -- One person died and more than 20 were injured after a bus carrying mainland tourists collided with a gravel truck in Taiwan, according to a tourism source Monday.

The accident occurred midday Monday when the bus, carrying a tour group from Jiangsu province, crashed with the truck on a highway section in Miaoli County and flipped over, said Man Hongwei, head of the Taipei office of the Association for Tourism Exchange Across the Taiwan Strait.

The sole fatality was the local bus driver. The tour guide, also from the island, is in a critical condition, said Man. Among the 26 mainland tourists, three suffered moderate injuries and 21 others sustained minor injuries. Two were unhurt.

The injured were taken to three hospitals for treatment. The tourists had been scheduled to stay in Taiwan until April 30.
