A U.S. army unit will arrive in Colombia in the coming days to help the Andean country's armed forces fight against drug trafficking for a four-month period, the U.S. embassy in Bogota said on Wednesday. The U.S. Security Force Assistance Brigade (SFAB) will arrive in Colombia in early June, the embassy said, without specifying the size of the unit. "SFAB's mission in Colombia is an opportunity to demonstrate our mutual commitment against drug trafficking and support for regional peace, respect for sovereignty and the lasting promise to defend shared ideals and values," said U.S. Southern Commander Admiral Craig Faller in a statement.
