Michael Fallon authorised use of RAF Lakenheath for US air raid on Daesh camp
A US air raid on an Islamic State training camp in Libya was launched from an RAF base in Suffolk.
The attack, launched from RAF Lakenheath on Friday, has been welcomed by Defence Secretary Michael Fallon.
He said: "I welcome this strike that has taken out a Daesh (Islamic State) training camp being used to train terrorists to carry out attacks.
"I was satisfied that its destruction makes us all safer and I personally authorised the use of our bases."
A key Tunisian extremist is believed to have been killed in the attack on the camp, near the Tunisian border.
US officials added that around 60 militants were present at the site when the war planes struck.
In Libya, local officials estimated that more than 40 people were killed with more wounded.
The Obama administration has previously vowed to strike key IS targets in Libya when opportunities arise, h owever, the strike did not appear to mark the start of a sustained US air campaign in the country.
Earlier this month UK foreign office minister Tobias Ellwood confirmed that RAF war planes have already been involved in flying missions over the country but gave no further details.
He said the UK was prepared to provide advice, support and training to the Libyan military if political agreement could be reached on the formation of a new government of national unity.
But he said there were no plans to commit British troops directly against IS.
