"Massive Group of Migrants Embark on Journey North from Southern Mexico"

Around 3,000 migrants began a mass protest procession through southern Mexico to demand the end of detention centers like the one that caught fire last month, killing 40 migrants. The migrants are mainly from Central America, Cuba, Venezuela, Ecuador and Colombia. Mexican authorities have used paperwork restrictions and highway checkpoints to bottle up tens of thousands of frustrated migrants in Tapachula, making it hard for them to travel to the U.S. border. The migrants are demanding the dissolving of the country’s immigration agency, whose officials have been blamed — and some charged with homicide — in the March 27 fire.
