Migrant caravan's long journey to U.S. border

Hondurans fleeing poverty and violence, rest before moving in a caravan toward the United States, outside a bus station.

More than 64 percent of Honduran households live in poverty, and San Pedro Sula has one of the world's highest murder rates.

More than 1,000 people, including families and women carrying babies, walk towards the U.S.

The migration began to swell after local media coverage of the initial group whose members had agreed to depart together Friday from a bus station in San Pedro Sula, one of the most dangerous cities in Honduras.

Hundreds more soon joined the ranks, wagering a mass exit could improve their chances for getting over borders. Many had already planned to leave Honduras and also felt traveling in numbers could lessen chances of falling victim to robbery and assault that often plague migrants.

More Honduran migrants tried to join the caravan of several thousand, trekking through Guatemala defying calls by authorities not to make the journey after U.S. President Donald Trump threatened to cut off regional aid in reprisal.

As some 3,000 Hondurans made their way through Guatemala, attention turned to Mexico, after U.S. President Donald Trump threatened Thursday to close the U.S.-Mexico border if authorities there fail to stop them — a nearly unthinkable move that would disrupt hundreds of thousands of legal freight, vehicle and pedestrian crossings each day.
