US border under pressure as caravan arrived

Soldiers from the Kentucky-based 19th Engineer Battalion work in a public park in Laredo, Texas, where they are installing barbed and concertina-wire on November 17, 2018. The soldiers are some of the thousands of US troops deployed to the US-Mexico border as part of a mission ordered by President Donald Trump to toughen the frontier and provide engineering and logistical support to Customs and Border Protection agents.
