Authorities are asking Reynosa residents to be careful following reports of a series of shootouts between armed men and soldiers.
Reynosa residents turned to the social media network Twitter to report the first rounds of gunfire in the Colonia Rodriguez around 1 p.m. Thursday.
Many residents reported gunfire as well as soldiers and armed men clashing in the streets in neighborhoods in and around downtown Reynosa.
But the City of Reynosa issued an alert asking people to avoid the Colonia El Olmo in the city's northwest side around 1:30 p.m. Thursday.
It's not clear if there were any injuries or casualties but the incidents remain under investigation.
