A Royal Navy warship successfully repelled a drone attack by Houthi rebels in the Red Sea on Saturday, the defence secretary has announced.

Grant Shapps said the UK remained “undaunted” after the assault by the Iran-backed rebel group, adding that the government’s commitment to protecting innocent lives and the freedom of navigation was “absolutely unwavering”.

None of the crew were injured and the HMS Diamond was undamaged, the Ministry of Defence said in a statement.

The ship shot the drone down using its own missile defence system.

It is not the first time the HMS Diamond has been targeted by the group.
