Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a coordinated attack against an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), as stated by the UK's MoD.
The location, pinpointed through surveillance, was believed to be containing munitions and bombs, the release indicated, and was positioned in hills just north of Palmyra in central Syria.
"Our aircraft employed precision-guided Paveway IV munitions to hit a number of access tunnels providing entry to the facility... preliminary assessments are that the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the attack late on Saturday and every plane involved made a safe return, the MoD added.
The British jets were supported by a Voyager refuelling tanker.
Daesh - also known as ISIS - imposed extremist governance over significant areas in Syria and Iraq until 2019.
"This action underscores the UK's leading role, and determination to operate in unison with our allies, to eradicate any resurgence of Daesh and their dangerous and violent ideologies in the area," Britain's Defence Chief the Defence Secretary stated.
British military aircraft have conducted surveillance missions over Syria to "forestall any attempted comeback" of Islamic State after its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces who took part in this mission for their skill and their courage," he said. "They were part of numerous UK service members on duty over Christmas and New Year. This operation, to take out dangerous terrorists who pose a risk to our way of life, demonstrates how British military are ready to step up, continuously, keeping Britain secure within its borders and strong abroad."
Last December, the US military executed what it described as a "massive strike" targeting Islamic State objectives in the country, after an ambush resulted in the deaths of two US servicemembers and a civilian linguist in the Palmyra area.
The United Nations says Daesh still maintains between 5,000 and 7,000 militants in Iraq and Syria.
