Images of migrants on Texas streets in freezing temperatures spark concern

One video shows dozens of migrants wrapped in thin blankets as they slept on El Paso streets amid surge of arrivals in city

Images of migrants wrapped in blankets and sleeping on the streets of El Paso in freezing temperatures have raised welfare concerns as they circulated online this week amid a surge of people arriving in the west Texan city.

Over the last few days, thousands of migrants, including many hailing from Nicaragua, Cuba and Venezuela, huddled along the waters of the Rio Grande, while others waded across the river from El Paso's sister city on the Mexican side of the border, Ciudad Juarez, to cross into the US.
