Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a joint strike targeting an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), as stated by the UK's MoD.
The facility, pinpointed through intelligence, was believed to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just north of the historic site of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to target a number of approach shafts providing entry to the site... preliminary assessments suggest the strike was effective," the MoD said.
There was no evidence of any civilian casualties in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - also known as Daesh - established extremist governance over large swathes of Syria and Iraq until 2019.
"This operation demonstrates the UK's leading role, and resolve to operate in unison with our partners, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the minister stated.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State subsequent to its defeat at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to all the members of British forces who took part in this mission for their expertise and their valour," Healey said. "They were part of numerous UK service members on duty over Christmas and New Year. This mission, to eliminate terrorist threats who threaten our way of life, highlights how British military are ready to step up, continuously, protecting the UK at home and influential overseas."
Last December, the US military conducted what it described as a "large-scale strike" against IS targets in Syria, following an assault resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The U.N. says IS still maintains roughly 5-7 thousand fighters in both countries.
