Direct assaults in three separate instances in the northeast Mexican state of Nuevo Leon led to a total of two armed suspects dead, and several wounded, according to Mexican news sources.
In Monterrey, a police station on Avenida Felix Uresti Gomez was attacked when a grenade detonated in front of a guard house wounding one police agent. Damage was limited to window glass and some lighting. Reports say a lone suspect threw the grenade into the guard station then fled the scene.
Later international reports put the wounded total to four and said two armed suspects were involved in the assault.
Also, early Sunday morning a detachment of the Mexican 7th Military Zone fought a battle with armed suspects in General Teran which lasted 30 minutes. Reports say the army patrol came across a convoy of trucks, the occupants of which apparently open fired on the soldiers. Two armed suspects died in the ensuing firefight.
Reports say about 10 other armed suspects managed to escape the scene without harm or arrest. Soldiers seized a single vehicle. At last report the military was conducting searches in the area for the remaining suspects.
General Teran is a town about 75 kilometers southeast of Monterrey.
Also, early Sunday morning a Monterrey police intelligence center, known as the C5, was assaulted with small arms by unidentified armed suspects.
The assault was of short duration, so the building suffered minor damage and no one was reported hurt in the attack.
The center is on the National Highway to Reynosa. Tamaulipas. Following the attack snipers were deployed nearby as a countermeasure to future attacks.
On Saturday at about 1500 hrs, Mexican federal agents with army detachments deployed in the university town of San Nicolas de los Garza at the stadium of Universidad Autonoma de Nuevo Leon for a security exercise.
Mexican security authorities denied the exercise was because of threats of an attack on the metric football game between two university teams.
San Nicolas de los Garza is a suburb of Monterrey.
