(Al Jazeera) Mexican authorities said on Friday that five attackers have died in a clash with soldiers in the northern border state of Tamaulipas, bringing the state’s death toll in two days of presumed gang-related violence to 29.

A group of armed assailants attacked a military patrol Thursday on a highway near the Rio Grande, wounding one soldier, according to a Tamaulipas state official who was not authorised to be quoted by name.

The official said the patrol returned fire, killing five assailants.
