Bus crash in Mexico leaves 18 passengers dead

At least 18 people died in western Mexico when a passenger bus plunged off a highway into a ravine on August 3, state officials said, adding the passengers were mostly foreigners and some were heading for the U.S. border.

En route to the northern border town of Tijuana, the bus had been carrying around 42 passengers, including citizens from India, Dominican Republic and African nations.

The bus driver has been detained, the Nayarit state government said in a statement, with authorities suspecting him of speeding round a bend in the road.

Officials said they were still working to identify those who had died on Thursday afternoon.

Around 20 people have been taken to hospital to treat injuries, with one woman's condition described as "delicate," the state government said.

The bus crashed near Barranca Blanca on the highway outside state capital Tepic, officials said. Rescue has been "extremely difficult", as the ravine was some 40 meters deep.
