Thousands of migrants from Honduras slowly push north as they attempt to cross into Mexico via Guatemala, en route to the U.S. border. The migrant caravan is increasingly becoming a humanitarian crisis as the migrants battle heat, exhaustion and a dangerous passage.
The Mexican government has closed its southern borders indefinitely. President Donald Trump has threatened to close the U.S.-Mexico border if the migrant caravan continues north.
But the migrants vow to keep pushing through, finding alternative routes north. The following are some of the harrowing scenes developing around the border between Guatemala and Mexico.
