Hundreds of Central American migrants who traveled in caravans to Tijuana are requesting assistance to go back home or filing for asylum in Mexico rather than seeking to legally enter the U.S., Mexican authorities said.

The spike in such requests over the past two days comes as migrants are facing diminishing prospects to get to the U.S. soon and after violent clashes Sunday between migrants and U.S. security officers at the border.

About 200 migrants have filed for voluntary repatriation with Mexican authorities over the past two days in Tijuana, said a senior officer of Mexico’s migration agency. No such requests were made in the prior week.

A group of 105 migrants, most of them from Honduras, departed by plane from Tijuana’s airport on Tuesday, said Gerardo Elías García, head of Mexico’s migration agency.

Another group of 98 migrants are being deported to their home countries in buses, because they were among those who attempted to force their way across the border into the U.S., Mr. Garcia said Tuesday.
