@foxnews: The State Department has issued a new worldwide caution urging Americans to reconsider travel to the Middle East as tensions continue to escalate. The warning comes after two U.S. service members were killed, four were wounded and one remains missing following an Iranian missile strike on a U.S. base in Jordan. Officials cite the potential for further escalation as Iran expands attacks across the region, targeting U.S. forces and key American allies in Jordan, Kuwait and Bahrain.
