President Donald Trump said Monday the United States will start cutting aid to Guatemala, Honduras and El Salvador as a caravan of thousands of mostly Honduran migrants rolled on regardless toward the US border.
The United Nations said more than 7,000 people were now heading toward the United States, as more migrants joined the original group, including some Central Americans who were already in Mexico.
Trump meanwhile kept up his almost-daily Twitter attacks on the approaching caravan, calling it a national emergency, and saying he had alerted the US border patrol and military.
Mexican authorities had managed to block the migrants on the Mexico-Guatemala border after they burst through a series of barriers on the Guatemalan side on Friday. But many later crossed the river below in makeshift rafts before marching north.
The caravan resumed its journey Monday in the state of Chiapas in southern Mexico, setting out from Tapachula, near the border, for the town of Huixtla, around 40 kilometers (25 miles) away.
Many of the migrants had spent the night on the town square or the street, wary of the shelters set up by charities and the government. Moving in a massive ebb and flow, they set out on foot or hitched rides with passing cars and trucks.
