Four Mexican soldiers drowned Tuesday near the Rio Grande when their truck overturned into an irrigation canal, officials said.
The Tamaulipas state security co-ordination group said the accident occurred in Reynosa across the border from Texas. It identified the victims as three members of the newly created National Guard and the fourth a member of the army.
The soldiers were on patrol against organized crime when the accident occurred, according to a statement.
Tamaulipas Gov. Francisco García Cabeza de Vaca offered his condolences to their families and the military via Twitter.
