 The U.S. Embassy in Lebanon is warning Americans to strongly reconsider travel to the country. As NPR's Jackie Northam explains, the move comes amid growing tensions between Israel and Iran-backed Hezbollah militants in southern Lebanon.

It urged U.S. citizens not to travel to southern Lebanon, the Lebanon-Syria border region, or to refugee settlements.
