U.S. issues travel warning for Israel with Iran expected to attack any moment and fear Gaza war could spread

Israel is bracing for a worst-case scenario that U.S. officials believe could materialize within just hours — the possibility of a direct attack on Israeli soil by Iran in retaliation for a strike almost two weeks ago that killed seven Iranian military officers. Iran has vowed to take revenge for Israel killing its commanders, who were hit by an April 1 strike on the Iranian embassy in Syria’s capital.

Two U.S. officials told CBS News that a major Iranian attack against Israel was expected as soon as Friday, possibly to include more than 100 drones and dozens of missiles aimed at military targets inside the country. The officials said it would be challenging for the Israelis to defend against an attack of such a magnitude, and while they held out the possibility that the Iranians could opt for a smaller-scale attack to avoid a dramatic escalation, their retaliation was believed to be imminent.

Tehran has not indicated publicly how or when it will return fire — so it’s unclear how far Iran’s leaders will go. If they decide to carry out a direct attack on Israel, there’s fear it could blow Israel’s ongoing war against Iranian ally Hamas up into a much wider regional conflict.
