The American Consulate in Matamoros has issued a warning following a string of grenade attacks, including two of them against schools.
Residents have been using the #Matamoros hashtag of Twitter to report the attack over the past few days.
The Reforma News Agency reported that morning a high school and a college were both attacked on Monday morning.
No injuries were reported but residents said there were only property damages.
Nobody has claimed responsibility for the attacks but Tamaulipas remains a battleground state between former allies the Gulf Cartel and the Zetas.
Consulate officials issued a warning for American citizens south of the border on Monday afternoon.
According to the warning, there have been a series of attacks using explosive devices since Thursday.
The majority of the attacks have been in or near the Fraccionamiento Victoria on the city's southside but have not been limited to the area.
The consulate is asking its employees to exercise appropriate caution.
