Mexico has significantly increased the number of National Guard forces at its southern border with Guatemala. The question: has it succeeded in slowing the flow of migrants trying to reach the U.S.?

In what may be the start of a major security overhaul, Mexico's president has launched a 70,000-strong National Guard force. But their role remains unclear, as does their training and make up.

Mexico pledged to ramp up immigration enforcement and let asylum-seekers wait on its side of the border. But on its own southern border, migrant detention centers are already overcrowded.

Mexico says it began deployment of National Guard troops to its southern border Wednesday. Its foreign minister says the U.S. and Mexico agreed to review the success of the enforcement in 45 days.

Mexico promised to tighten security along its southern border to prevent migrant crossings — specifically sending national guard troops — prompting President Trump to call off proposed tariffs.

As part of tariff negotiations with the U.S., Mexico plans to stop the flow of migrants from Central America. Mexico is still finding the resources needed to harden its border with Guatemala.

Thousands of migrants are camped in Tijuana, Mexico, after U.S. authorities fired tear gas on those who tried to rush the San Ysidro border crossing. Hopes of applying for asylum in the U.S. dim.

U.S. Customs and Border Protection closed the port of entry at San Ysidro on Sunday. The move came just hours after President Trump tweeted, "No crossings!"

Thousands of Central American migrants who have traveled weeks to get to the U.S. border are in Tijuana facing an uncertain future. Mexicans there resent them and the asylum process could take months.

While some residents of the northern Mexican city have said "all migrants are welcome," a group of protesters this weekend demanded they be kicked out.
