On Friday, President Andres Manuel Lopez Obrador of Mexico said that a caravan of over 2,000 Honduran migrants, heading through Guatemala to Mexico, was motivated by political interference. The caravan’s ultimate aim is to reach the United States. 

He ordered the Mexican military to deploy along the country’s southern border to block the caravan from reaching Mexico’s borders. The Mexican military and National Guard will deploy hundreds of military and immigration personnel to its border to prevent the caravan entering the country, a senior government official said.

“They’re not going to cross,” Francisco Garduno, the head of the Mexican migration authority, said to media members. He added that the migrants must “respect the immigration law.”

Obrador believes that the timing of the caravan’s movement is tied to the contentious U.S. presidential election in which immigration is one of the key issues.
