The United States believes that Iran and its proxies, like Hezbollah, are still planning attacks on Israel.
This assessment comes after Hezbollah launched a barrage of rockets and drones over the weekend, targeting Israel.
The US is working with Israel to defend against these threats and has sent two carrier strike groups to the region.
Iran has threatened to retaliate for the deaths of several of its officials in Tehran and Beirut, which Israel is suspected of being involved in.
