U.S. officials say Israel has narrowed down its targets for strike on Iran

U.S. officials believe Israel has narrowed down what they will target in their response to Iran's attack, which these officials describe as Iranian military and energy infrastructure.

There is no indication that Israel will target nuclear facilities or carry out assassinations, but U.S. officials stressed that the Israelis have not made a final decision about how and when to act.

The region has been on edge awaiting Isreal's response to an Iranian missile barrage launched on Oct. 1, which Iran said was in response to Israel's invasion of Lebanon and the assasination of its allies, including Hamas' Ismail Haniyeh in Tehran, and Hezbollah's powerful leader, Hassan Nasrallah in Beirut.

Iran's attack caused little damage in Israel.

The U.S. does not know when Israel's response could come but officials said the Israeli military is poised and ready to go at any time once the order is given.
