Venezuelan migrants come into contact with Colombian guerrillas after crossing the river border. The migrants have turned up among captured and killed rebels, a Colombian military commander tells NPR.
The migrants are encountering crowded shelters, strained resources, and residents who are not as generous as they were with a previous caravan that was making its way to the U.S.-Mexico border.
The attack, which left several people dead, was a reminder of the Colombian capital's violent history with guerrilla groups and drug cartels. No group claimed responsibility for Thursday's attack.
The caravan, which could consist of up to 2,000 migrants, began its journey from Honduras on Monday. The migrants have already become symbols in the ongoing battle over border security.
President Andrés Manuel López Obrador says his crackdown on stolen fuel is working, but long waits in several states persist, distribution bottlenecks continue and new acts of gas theft are reported.
