At least 18 people were killed and 10 were injured in a bus accident Saturday in the central Mexican state of Nayarit, according to local authorities, according to DPA. The bus driver apparently lost control of the bus, which went off the road and down a cliff or embankment, according to initial reports. The driver was suspected to have been driving too fast. Nayarit, about 800 kilometres north-west of Mexico City, is on the Pacific Coast.
