The U.S. embassy in Lebanon said on Wednesday that two American citizens were missing and appealed for information on their whereabouts.
The embassy said on its website two Americans -- who are believed to be journalists -- had not been heard from since October 1 when they left Beirut for the northern city of Tripoli, where anti-U.S. Sunni Muslim militant groups are active.
