Groups of Central American migrants have been converging on the Mexican border city for days in their quest to gain entry to the United States.
Soon after the migrants began their midday march to the border in Tijuana, Mexico, they were met by Mexican federal police officers at a bridge that leads to the San Ysidro border crossing, through which millions of people and vehicles pass each year. Many hope to apply for asylum in the US, but agents at the San Ysidro entry point are processing fewer than 100 asylum petitions a day. American authorities shut down the nation's busiest border crossing at San Ysidro for several hours at the end of the Thanksgiving weekend.
"Mexico should move the flag waving Migrants, many of whom are stone cold criminals, back to their countries".

Lurbin Sarmiento, 26, of Copan, Honduras, walked back to the sports complex with her 4-year-old daughter shaken from what had unfolded a short time earlier at the Tijuana River and US border.

Within an hour on Sunday, the group from the caravan that rushed toward the border largely dispersed.
A group of Central American migrants, mostly Hondurans, climb a metal barrier. Meanwhile, Tijuana's municipal government said that more than three-dozen migrants were arrested for disturbing the peace and other charges stemming from the march and what followed. The legal bar for claiming asylum is high and generally requires applicants to show a specific risk of persecution based on factors such as race, nationality, politics or religion. Residents of Tijuana work, study and visit the United States each day, and the border closures affect them, too, Juan Manuel Gastélum Buenrostro said on Twitter on Sunday.
