The U.S. has prepared for what could be significant attacks by Iran or its proxies in the Middle East as soon as this week, White House national security spokesperson John Kirby said on Monday.
Kirby told reporters that the U.S. had increased its regional force posture in recent days and shared Israel's concerns about a possible Iranian-backed attack after Iran and Palestinian Islamist group Hamas accused Israel of carrying out the assassination of a Hamas leader in Tehran last month.
