SAN PEDRO SULA, Honduras (AP) — Several hundred Honduran migrants, many carrying young children, set out in a caravan for that country’s border with Guatemala on Wednesday, hoping to reach the United States.

Some of those who gathered at the San Pedro Sula bus station said they can’t support their families with what they can earn in Honduras and are seeking better opportunities.

Most boarded buses before dawn that would carry them to towns on the Guatemalan border. Others walked through the rain, some pushing strollers or carrying sleeping children in their arms.

Nohemy Reyes, who waited at the bus station with one of her five children sleeping on floor beside her, said her country’s economic straits are driving her north.

“The economic situation is very difficult,” she said. But if she finds the U.S. border closed, she said, she will return to Honduras.

U.S. President Donald Trump this week threatened to close the U.S.-Mexico border before changing course and threatening tariffs on automobiles produced in Mexico if that country does not stop the flow of Central American migrants.

U.S. border facilities have been overwhelmed by the number of migrant families. U.S. Customs and Border Protection announced this week that 53,000 parents and children were apprehended at the southern border in March.

Department of Homeland Security Secretary Kirstjen Nielsen resigned this week and was replaced by U.S. Customs and Border Protection Commissioner Kevin McAleenan in an acting capacity.

Trump on Tuesday said he isn’t planning on reinstating his controversial family separation policy. Last summer, more than 2,500 children were separated from their families before a judge ordered them reunited.

Miguel Angel Reyes of San Juan Pueblo, Honduras, said his country’s violent crime was one factor in his decision to leave, but mostly he was looking for a way to provide for his wife and four children.

“I’m going because the situation is really hard here in Honduras,” said the field worker. “We can’t take it anymore. There’s a lot of suffering, no work.”
