Mexican government officials in Tijuana reported that they have met and treated more than 3,600 migrants who are part of the controversial caravan that began in Honduras last month en route to the southern border.

The migrants are being temporarily housed in two locations along the US-Mexico border, with many seeking asylum in the United States.
