Migrants who are part of the ‚migrant caravan‘ walk at dusk on their way to Tijuana on November 20, 2018 near Mexicali, Mexico. Parts of the migrant caravan have been arriving to Tijuana after traveling through Central America and Mexico to reach the U.S. border. A US federal judge has temporarily blocked President Trump’s order which attempted to deny migrants the possibility of asylum if they cross the border illegally.
