US detained nearly 1m migrants in 12 months

NEW YORK: US border agents arrested or stopped nearly one million undocumented migrants at the southern border with Mexico in the last 12 months, the most in more than a decade, a top official said Tuesday. The surge came amid President Donald Trump's tough efforts to halt illegal immigration, which began to show results only in the last three months, when border arrests plummeted.

Acting Director of Customs and Border Protection (CBP) Mark Morgan said migrants arrested at the border fell to just over 52,000 in September, the final month of the 2019 fiscal year, down from over 144,000 in May and the lowest monthly figure in one year. The surge came mainly from Central American migrants fleeing poverty and violence, crossing in large groups and family units into the US from Mexico and turning themselves in to ask for asylum. For most that meant being processed by immigration officials and then released to await a hearing on their asylum claim, but they usually disappeared into the US interior hoping to settle.

The Trump administration has stepped up efforts to discourage an exodus from Honduras, Guatemala and El Salvador by asking Mexico to impede their transit and requiring them to apply for asylum in the first country they enter - meaning either Guatemala or Mexico. "CBP is continuing to collaborate with our foreign partners - particularly, Mexico, El Salvador, Guatemala and Honduras - to address this as a regional crisis," Morgan said in a White House briefing. The administration has ordered the expulsion of any asylum seekers back to Mexico, and is fighting a court injunction blocking the implementation of that order.
