At least 42 people are dead after a bus fell into a ravine in southern Morocco on Tuesday, the BBC reports.

More than 20 other people were injured in the fall, some seriously.

The bus, which had been travelling from Marrakesh to Zagora, reportedly crashed near the town of Zerkten in Haouz province.

Most of the casualties were Moroccan, the BBC says. It's not clear whether any tourists or foreigners were on board.

Morocco is plagued with road accidents. They killed 4,000 people last year, up 11.6% from the year before.
