Iranian forces say they have struck a US naval base in Bahrain, as Iran launched strikes across the region in retaliation for a “massive” and ongoing attack against it by the US and Israel.

Huge plumes of black smoke were seen rising from an area near the headquarters of the US Navy’s Fifth Fleet in Manama, Bahrain. The extent of any damage is unclear and the US has not commented.

Elsewhere across the region, the UAE, Qatar and Kuwait – all home to US military bases – said they have intercepted missiles in their air space.

In Doha, Qatar’s defence ministry said it had intercepted several missiles apparently targeting the al-Udeid air base, the largest American base in the region.
