RAF Typhoon fighter aircraft have operated alongside France's air force in a combined operation against an underground arms cache in Syria operated by the Daesh militant organization, per a report from the UK's MoD.
The facility, pinpointed through surveillance, was assessed as containing munitions and bombs, the release indicated, and was located in mountainous terrain just north of Palmyra in Syria's central region.
"The RAF jets used precision-guided Paveway IV munitions to strike a number of access tunnels down to the depot... early reports suggest the strike was effective," the MoD said.
There was no sign of any civilian casualties in the strike on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - referred to as Daesh - established jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our allies, to stamp out any revival of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary stated.
RAF aircraft have carried out surveillance missions over Syria to "forestall any attempted resurgence" of the group following its defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I extend gratitude to every member of our armed forces involved in this strike for their professionalism and their bravery," he said. "They were among numerous UK service members on duty over the holidays. This action, to remove dangerous terrorists who endanger our way of life, highlights how British military are prepared to act, continuously, ensuring Britain's security within its borders and influential overseas."
In December, the United States armed forces conducted what it described as a "large-scale strike" against IS targets in Syria, following an ambush resulted in the deaths of two US servicemembers and a civilian linguist in the Palmyra area.
The UN reports Islamic State still has roughly 5-7 thousand militants in both countries.
