Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a combined operation on an underground arms cache in Syrian territory used by the Daesh militant organization, per a report from the UK's MoD.
The site, located using intelligence, was believed to be containing munitions and bombs, the announcement noted, and was located in hills just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a series of access tunnels providing entry to the depot... initial indications suggest the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - enforced militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and commitment to stand shoulder to shoulder with allied nations, to eradicate any re-emergence of Daesh and their violent and radical beliefs in the area," Britain's Defence Chief the minister said.
UK warplanes have performed surveillance missions over Syria to "prevent any efforts to regroup" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I extend gratitude to all the members of British forces involved in this operation for their skill and their courage," Healey said. "They were part of numerous British troops on duty over the festive period. This operation, to remove terrorist threats who endanger our safety, demonstrates how British military are ready to step up, throughout the year, protecting the UK at home and powerful internationally."
In December, the United States armed forces conducted what it termed a "massive strike" on Islamic State objectives in the country, following an attack claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The UN estimates Islamic State still has between 5,000 and 7,000 combatants in Iraq and Syria.
