11 dead, 4 injured in Mexico arson attack

The incident occurred during the early hours of Saturday morning, after an unknown person, allegedly drunk, threw a lit object at the doors of a cantina after being expelled by the staff, the Sonora Attorney General's Office detailed in a statement on Saturday.

"According to several witnesses, the young male was disrespecting women in the bar, so he was removed, and then returned and threw apparently some kind of 'Molotov' bomb at the doors of the building, which caused the incident," said the statement.

Among the deceased were seven men and four women, while the injured were taken to hospitals in the city and the United States.

The ministerial criminal investigation agency and expert services are working at the site, in coordination with the federal, local and municipal governments, to locate the alleged perpetrator.

Calling the attack "a tragedy," Mayor of San Luis Rio Colorado Santos Gonzalez Yescas said Civil Protection personnel and municipal firemen were aiding the investigations.
