HAVANA (AP) — The leader of a delegation of Republican senators visiting Cuba says the opening of a U.S. embassy in Havana for the first in 54 years is “imminent.”

Sen. Jeff Flake of Arizona was in Havana made a short visit to Havana with fellow senators Susan Collins of Maine and Pat Roberts of Kansas on a fact-finding mission and to gauge progress on talks to restore normal diplomatic relations between the U.S. and Cuba.

After meeting with Cuban officials, Flake predicted Saturday that the opening of both a Cuban embassy in Washington and a U.S. embassy in Havana will occur in the very near future.
