MEXICO CITY, March 11, 2025 (BSS/AFP) - At least 32 people were killed on Monday in two separate bus crashes in Mexico, authorities said.

A bus turned over along a highway in southern Mexico's Oaxaca state, killing 18 people, the state government said in a statement. Twelve others remained in hospital.

Authorities will launch an investigation into the cause of the accident, which happened near the community of Santo Domingo Narro, it added.

Mexican media reported that the victims were supporters of the ruling left-wing party who were returning from a Sunday rally in Mexico City, where President Claudia Sheinbaum highlighted her opposition to US President Donald Trump's trade tariff policy.

In the country's north, 14 people died in a fiery collision between a tractor-trailer and a bus carrying passengers from the US state of Texas, civil protection authorities in Durango state said.

Of the 24 people traveling in the bus, only 10 managed to get out alive, it said.

Deadly road accidents are common in Mexico due to high speeds, poor vehicle or road conditions and driver fatigue. At least 15,000 people are killed on the roads every year, according to multiple sources.

Thirty-eight people died in a road accident on February 8 when a truck collided head-on with a bus in Mexico's southeastern state of Campeche, according to authorities.
