The HMS Diamond shot down the drone - the first time in decades that the Royal Navy has taken out an aerial target in anger

A Royal Navy destroyer warship has shot down a suspected attack drone over the Red Sea, the Defence Secretary has said.

The HMS Diamond was only sent to the region two weeks ago amid growing international concern about the threat to shipping.

The Type 45 destroyer was said to have destroyed the suspected attack drone targeting merchant shipping - with a Sea Viper missile.

It is believed to be the first time that the Royal Navy has shot down an aerial target in anger since the First Gulf War in 1991.

Grant Shapps said it was believed merchant shipping in the Red Sea was the intended target, in the latest such confrontation in the key global shipping route.
