Royal Air Force Typhoon FGR4s have conducted a mission with French aircraft in a combined operation targeting an underground arms cache in Syrian territory used by the Islamic State group (IS), according to the British defence ministry.
The location, located using surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was located in hills just to the north of Palmyra in central Syria.
"Our fighter planes used Paveway IV guided bombs to hit a number of access tunnels providing entry to the facility... preliminary assessments indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the strike on Saturday evening and each participating jet returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
Daesh - also known as the so-called Islamic State - imposed militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates our UK leadership, and resolve to operate in unison with our partners, to stamp out any resurgence of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief John Healey said.
RAF aircraft have conducted patrols over Syria to "forestall any attempted resurgence" of the group after its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank every member of the UK armed forces participating in this operation for their skill and their bravery," the Defence Secretary said. "Including them were thousands of British personnel stationed over the festive period. This operation, to take out dangerous terrorists who endanger our security, highlights how our armed forces are prepared to act, all year round, protecting the UK at home and influential overseas."
During December, the United States armed forces executed what it termed a "major assault" on Islamic State objectives in the country, subsequent to an assault killed two American soldiers and a civilian linguist in Palmyra.
The UN reports Islamic State still boasts roughly 5-7 thousand combatants in Syria and Iraq.
