A caravan of Central American migrants marching into Mexico bound for the United States grew to at least 5,000 people Sunday despite threats from President Donald Trump to use the U.S. military to seal the border.

The throng, many from Honduras, streamed across a bridge over the Suchiate River connecting Guatemala with Mexico.

The Los Angeles Times, citing Gerardo Hernandez, head of the local government’s emergency services, reported that 7,233 immigrants had registered over the past three days at a shelter in Ciudad Hidalgo. Hernandez said his agency has been asked to help provide the immigrants with food and shelter.
