Around 150 migrants at the U.S.-Mexico border in Tijuana began the new year fleeing tear gas launched by border agents early Tuesday morning, AP reports.
The big picture: This is the second recent instance of tear gas being used on crowds of migrants, including women and children, who have travelled to the U.S. in "caravans" — many to seek asylum. Past administrations have also used tear gas, but it has been a rare, last resort. The instance highlights the Trump administration's often harsh, ongoing attempts to combat immigration.
