RAF Typhoon FGR4s have operated alongside French aircraft in a joint strike against an subterranean weapons facility in Syria operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, pinpointed through intelligence, was believed to be housing weapons and explosive materials, the release indicated, and was located in mountains just to the north of the historic site of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a series of entry passages leading to the facility... initial indications are that the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the strike late on Saturday and all the aircraft made a safe return, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - also known as ISIS - enforced extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores our UK leadership, and determination to work closely with our allies, to stamp out any resurgence of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister remarked.
UK warplanes have conducted patrols over Syrian airspace to "prevent any attempted comeback" of the group following its military defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank all the members of our armed forces involved in this operation for their expertise and their courage," Healey added. "They were part of thousands of UK service members on duty over the holidays. This action, to remove terrorist threats who threaten our way of life, demonstrates how British military are prepared to act, continuously, ensuring Britain's security within its borders and strong abroad."
During December, the US military executed what it called a "massive strike" against Islamic State objectives in the country, after an ambush killed two American soldiers and a civilian linguist in the Palmyra area.
The U.N. reports IS still boasts between 5,000 and 7,000 fighters in Syria and Iraq.
