Welcome to our live coverage of the crisis in the Middle East.

Iran says it has launched a missile attack at an airbase in Jordan hosting US forces, after also targeting Kuwait and Bahrain. The Revolutionary Guards said missiles have targeted the Muwaffaq Salti airbase, which is known to host US F-35 fighter jets and other aircraft.

Neither Jordan nor the US has acknowledged any attack, but if confirmed it would likely be the first time that Iran has targeted Jordan since the start of the ceasefire in April.

The US strikes on Iran followed the downing of a US Apache helicopter over the strait of Hormuz, from which two crew members were rescued in a stable condition. In a post on social media Trump said the US “must” respond to the helicopter crash.

Here is the latest:

• The US launched multiple waves of strikes on Iran in response to a military helicopter crash off the strait of Hormuz that Donald Trump said Iran had downed. The Associated Press reported that the Apache helicopter that crashed went down after colliding with an Iranian drone, but it was not clear whether the collision was intentional.

• US strikes were reported across Iran’s southern coast, on the strait of Hormuz. After more than three hours of military action, US central command (Centcom) said strikes were “completed”, adding that the US remained ready to defend against “unjustified Iranian aggression.”

• Soon after, Iran launched retaliatory attacks against the US, according to the countries state media, which said American bases in the region and the US fifth fleet in Bahrain were targeted with drones. Kuwait and Bahrain issued air raid alerts and reported that air defences were active in repelling attacks. Iran also claimed it had targeted a US base in Jordan with long range missiles.

• Iran’s foreign minister, Abbas Araghchi, said no attack would go “unanswered”, soon after the US launched strikes on Iran. Posting an image of the strait of Hormuz with the label, “Forever Persian Gulf”, Araghchi says that “despite its defeats on the battlefield, the U.S. opted to test our determination.”

• Five hours before the airstrikes, Trump had posted on social media that the US “must” respond to the helicopter crash, from which two crew members were rescued in stable condition. Before his social media post, however, Trump appeared to downplay the crash, telling the Wall Street Journal in a phone interview that it “wasn’t a big deal” and that “the pilot is fine.”

• Iranian state media reported that no air military operations have taken place in the strait of Hormuz over the past 24 hours, according to Reuters.

• Lebanon’s health ministry said 11 people were killed in Israeli airstrikes on the southern city of Tyre on Tuesday. The state-run National News Agency (NNA) had reported the first strike taking place not long before Israel’s military issued an evacuation warning for the entire city and surrounding areas ahead of strikes there.
