Mexico, Honduras, and Guatemala have reached a deal with the Biden administration to surge their security forces to their borders to help reduce a wave of migration to the U.S., White House Press Secretary Jen Psaki said Monday. Mexico will keep 10,000 troops stationed at its southern border. Neighboring Guatemala has sent 1,500 police officers and troops to its southern border with Honduras, and will put 12 internal checkpoints along a route taken by migrants. Honduras has deployed 7,000 security forces to its northern border. The agreement came after a record number of unaccompanied children tried to cross the U.S.-Mexico border. The Border Patrol encountered just under 170,000 migrants overall on the southern border in March, the most since March 2001.
