More than a dozen rockets have been launched against US targets by Iran, hitting two Iraqi airbases where American and coalition forces are based, Washington has confirmed.

Iranian state TV said that Tehran had launched "tens" of surface-to-surface missiles in the attack on the Ain al-Assad airbase, in the country's west, as revenge for the killing of Gen Qassim Soleimani and Abu Mahdi al-Muhandis in Baghdad last week.
