TAPACHULA, Mexico — Mexican state police killed four gunmen near the border with Guatemala, then pursued more suspects into that country in three armored police vehicles, where they engaged in a shootout in the streets of a border town. Authorities in both countries said Monday they were investigating.
The rare case of Mexican law enforcement crossing the border into Guatemala on Sunday in La Mesilla was captured by onlookers in videos widely circulated online. With the border crossing a short distance in the background, armed men in ballistic vests and carrying rifles can be seen shouting at the open driver side door of a Chiapas state police armored vehicle.
Suddenly, another such vehicle comes speeding through the border crossing from behind, scattering the armed men. The initial vehicle reverses back toward Mexico and a third armored police vehicle enters from a side street slamming a civilian vehicle into the side of the other armored police truck. Gunfire erupts with the police trucks and civilian vehicles getting hit by bullets.
All the while, a Guatemalan military truck with a soldier in the turret, sits in the middle of the melee.
It was the latest flare-up of violence along a section of the border that has become a flashpoint as rival Mexican drug cartels and their local affiliates battle for control of valuable smuggling routes for migrants, guns and drugs.
Asked about the events, Mexico President Claudia Sheinbaum said Monday that everything appeared to show that Mexican authorities entered Guatemala.
''They are investigating it and it is not all right that has happened,'' she said.
Chiapas state Gov. Eduardo Ramírez Aguilar criticized what he suggested were Guatemalan authorities protecting members of organized crime. His security chief, Oscar Aparicio Avendaño, told The Associated Press on Monday that police had used a drone to detect armed men crossing the border into Mexico.
