Migrant caravan in Mexico

A caravan of more than 1,000 migrants from Central America has arrived in Tapachula, southern Mexico, with the goal of reaching the United States. Encouraged by the Republican defeat of Donald Trump's party in the midterm elections, the migrants hope for a relaxation of American immigration policy. Their progress, however, remains uncertain, as previous caravans were dispersed by Mexican authorities before even leaving the border region with Guatemala.
