A chaotic situation on the Guatemala-Mexico border. Thousands of migrants from Honduras advanced on Mexico's southern border - as they marched to the United States. Mexican troops blocked the caravan as it arrived, forcing some to turn back. CGTN's Franc Contreras has more from Mexico City.

Caravan migrants torn down a border fence separating Guatemala from Mexico. Dozens of undocumented immigrants ran into Mexico before police officers deployed pepper spray -leaving the rest withdrawing from the border. Many are Central Americans participating in a migrant caravan that has traveled from Honduras through Guatemala and to southern Mexico.The incident happened as U.S. Secretary of State Michael Pompeo met with Mexico's Foreign Relations Minister Luis Videgaray. Videgaray said Mexico has called on the United Nations to help deal with immigration crisis.

LUIS VIDEGARAY CASO MEXICAN FOREIGN MINISTER "Mexico yesterday invited the United Nations to get involved in this process helping the Mexican immigration authority to decide each of the individual requests for refuge taking place now."

MIKE POMPEO US SECRETARY OF STATE "President Trump has been clear about the largest issue that we face today after having negotiated that deal. We are quickly reaching a point which appears to be a moment of crisis. Record numbers of migrants as Foreign Secretary Videgaray spoke about the importance of stopping this flow before it reaches the U.S. border."

The U.S. president took a different tone. On Thursday, at a campaign rally in the U.S. state of Montana, Donald Trump added immigration to the list of next month's mid-term election issues in the United States.

DONALD TRUMP US PRESIDENT "This will be an election of Kavanaugh, the caravan, law and order and common sense. It's going to be an election of those things."

Trump never talked about the causes of the problem. But the top diplomats from the United States and Mexico agreed - improving the economy in Honduras could help solve it. No one mentioned the ongoing political crisis in that Central American nation.

FRANC CONTRERAS MEXICO CITY "Some of the migrants in the caravan have been telling journalists they're not planning to go to the United States. Instead, they'll stay here in Mexico. They've heard the incoming President Andres Manuel Lopez Obrador will be creating jobs here. And that is what is attracting them. FC, CGTN, Mexico City."
