MEXICO CITY &#8212 A bus carrying tourists crashed in western Mexico on Saturday, killing at least 17 people, authorities said.

The bus was carrying 35 passengers from the resort city of Puerto Vallarta to Guadalajara when it ran off a mountain road and plunged into a ravine near the town of Compostela, about 125 miles from Guadalajara, the Nayarit’s state prosecutor’s office said in a statement.

At least 17 people were killed. Another 14 were injured, five seriously, the statement said.

Red Cross spokesman Miguel Langarica said 18 people were killed and 13 injured. It was not immediately possible to explain the discrepancy in the death tolls.

The driver, 28-year-old Magdiel Coronado, was also injured and hospitalized, authorities said.

Bus company spokesman Daniel Rios said the passengers had yet to be identified but that at least eight family members were Mexicans legally living in Phoenix who were in the country for Independence Day celebrations. Four of them were injured and one, a 1-year-old child, was killed.
