As Mexico prepares to celebrate its September 16th Independence Day, life in Matamoros has come to a standstill.
Matamoros residents used the social media network Twitter to report gunfire and blockades around noon Thursday.
City officials confirmed a "situation of danger" was happening on the highway to Reynosa.
Residents posted several pictures of buses being used to block streets throughout the city.
The first reports came from the city's westside where blockades reported of Avenida Rigo Tovar and near the Soriana Laguneta.
More reports of blockades came in from downtown and one even took place several blocks away from the American Consulate.
Matamoros city officials had planned to hold festivities to celebrate Mexico's "Diez y Seis de Septiembre" or September 16th Indpendence Day.
The "El Grito de Independencia" or "Shout of Independence" at the Plaza Hidalgo is planned for 11 p.m. tonight.
An Independence Day parade is planned for 9 a.m. Friday.
It's not clear how the shootouts and blockades would affect those events or their attendance.
