A British RAF base in Cyprus has been targeted in a suspected drone strike - just hours after Sir Keir Starmer addressed the nation to confirm the UK would allow the US to use its bases to attack Iran.
While the BBC understands there were no casualties, the Ministry of Defence confirmed armed forces were responding to an attack at the RAF Akrotiri in Cyprus around 10pm UK time.
An MoD spokesperson said: "Our force protection in the region is at the highest level and the base has responded to defend our people.
"Our base and personnel continue to operate as normal protecting the safety of Britain and our interests."
A Cypriot government spokesperson told Reuters the incident involved an "unmanned drone, which caused limited damage".
The attack came shortly after Prime Minister Sir Keir Starmer gave a statement updating the UK's position in relation to the conflict.
He said the UK had granted a request from the US to use its military bases for what he described as "defensive" strikes on sites in Iran storing missiles.
The PM said that, learned from the "mistakes of Iraq", the UK was not involved in the initial strikes on Iran and would not join "offensive action" now.
Starmer added: "Our partners in the Gulf have asked us to do more to defend them, and it is my duty to protect British lives.
"We have British jets in the air as part of coordinated defensive operations which have already successfully intercepted Iranian strikes.
"But the only way to stop the threat is to destroy the missiles at source – in their storage depots or the launchers which used to fire the missiles.
"The United States has requested permission to use British bases for that specific and limited defensive purpose.
"We have taken the decision to accept this request – to prevent Iran firing missiles across the region, killing innocent civilians, putting British lives at risk, and hitting countries that have not been involved."

Yesterday, I spoke to you about the situation in the Gulf and explained that the United Kingdom was not involved in the strikes on Iran.
That remains the case.
Over the last two days Iran has launched sustained attacks across the region at countries who did not attack them.
They’ve hit airports and hotels where British citizens are staying.
This is clearly a dangerous situation.
We have at least 200,000 British citizens in the region - residents, families on holiday, and those in transit.
I ask all our people in the region to please register your presence and follow Foreign Office travel advice.
I know this is a deeply worrying time and we will continue to do all we can to support you.
Our Armed Forces who are located across the region are also being put at risk by Iran’s actions.
Yesterday Iran hit a military base in Bahrain, narrowly missing British personnel.
The death of the Supreme Leader will not stop Iran from launching these strikes.
Their approach is becoming even more reckless – and more dangerous to civilians.
Our decision that the UK would not be involved with the strikes on Iran was deliberate.
Not least because we believe that the best way forward for the region and for the world is a negotiated settlement.
One in which Iran agrees to give up any aspirations to develop a nuclear weapon.
But Iran is striking British interests nonetheless, and putting British people at huge risk, along with our allies across the region.
That is the situation we face today.
Our partners in the Gulf have asked us to do more to defend them, and it is my duty to protect British lives.
We have British jets in the air as part of coordinated defensive operations which have already successfully intercepted Iranian strikes.
But the only way to stop the threat is to destroy the missiles at source – in their storage depots or the launchers which used to fire the missiles.
The United States has requested permission to use British bases for that specific and limited defensive purpose.
We have taken the decision to accept this request – to prevent Iran firing missiles across the region, killing innocent civilians, putting British lives at risk, and hitting countries that have not been involved.
The basis of our decision is the collective self-defence of longstanding friends and allies, and protecting British lives.
That is in accordance with international law. And we are publishing a summary of our legal advice.
We are not joining these strikes, but we will continue with our defensive actions in the region.
And we will also bring experts from Ukraine together with our own experts to help Gulf partners shoot down Iranian drones attacking them.
I want to be very clear: we all remember the mistakes of Iraq.
And we have learned those lessons.
We were not involved in the initial strikes on Iran and we will not join offensive action now.
But Iran is pursuing a scorched earth strategy - so we are supporting the collective self-defence of our allies and our people in the region.
Because that is our duty to the British people.
It is the best way to eliminate the urgent threat and prevent the situation spiralling further.
This is the British government protecting British interests and British lives.
