Lebanon ? The U.S. Embassy in Lebanon issued an appeal for information Wednesday on behalf of the families of two missing Americans who have not been heard from since they checked out of a Beirut hotel a week ago.

Taylor Luck, 23, of Oak Park, Ill., and Holli Chmela, 27, reportedly of the Washington, D.C., area, have not been heard from since they left the hotel Oct. 1, telling friends they planned to travel north to the Lebanese port city of Tripoli and then to Syria, a statement from the U.S. Embassy said.

The two worked at the Jordan Times in the Jordanian capital, Amman, and had gone to Lebanon for a vacation during the five-day Muslim Eid festival marking the end of Ramadan, according to the newspaper’s editor in chief, Samir Barhoum.
