A second migrant caravan is forming in Guatemala, after the first one crossed into Mexico over the weekend and swelled to more than 7,000 people as it headed to the U.S.-Mexico border.

Thousands of Honduran migrants gathered in Guatemala near the border with Honduras on Tuesday to begin their journey north, the Wall Street Journal reported.

Estimates of the second grouping ranged from a few hundred Hondurans to a few thousand, the report said.

Thousands of migrants are already marching through Mexico, but are still more than a thousand miles away from the Texas border and could take a month or more to reach the U.S. border by foot.

The majority of migrants are from Honduras and are leaving to escape crime and poverty. Activists said the migrants have traveled in large caravans to avoid the dangers of human traffickers, who charge between $4,000 and $8,000 a person for the perilous trek to the U.S. border.

President Trump declared the first caravan a national emergency and threatened to cut or reduce aid to Central America countries for failing to stop the caravan from trying to enter the U.S.
