A bus carrying tourists from South Korea veered off a highway and fell part way down a cliff along Taiwan's eastern coast, injuring 15 people on board.

The bus's engine failed as it was travelling up a steep mountainous road in Taroko National Park in Hualian County.

The 13 South Korean tourists, a tour guide and local driver, were taken to hospital for treatment. Two had serious but non-life threatening injuries, the Associated Press reports.
