Death toll rising in Mexico bus crash

The number of victims killed in Sunday's bus crash in Mexico has risen to 32, Reuters said.

The bus ran off a wet freeway and slid into a ravine in Guerrero state, Mexico.

The crash happened Sunday just before 1 p.m. local time when the bus's brakes failed while it was traveling over a steep incline, reported CNN. The bus then fell 300 meters (983 feet) down an embankment.

A state government press release said the bus was headed to the town of Buenavista de Cuellar, 83 miles from the capital of Chilpancingo del Bravo, bringing passengers to a political rally, according to the Associated Press. The leftist Democratic Revolution Party also released a statement, expressing condolences for the party supporters killed in the crash and their families.

A Red Cross official said most of the people inside the bus were wearing T-shirts with the logo of Mexico's Labor Party (PT), which supports leftist presidential hopeful Andres Manuel Lopez Obrador, reported Reuters. The official also said the crash occurred in an area where it has been "raining very hard."

"According to information provided by the Guerrero state government, of the 26 people who died, 12 were adults, eight were youths and six were children, in addition to the 23 injured," the interior ministry said in a statement, reported Agence France-Presse.

According to EFE, those injured were transported to hospitals in the cities of Taxco, Iguala and Buenavista de Cuellar.
