Royal Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a combined operation on an subterranean weapons facility in Syrian territory employed by the IS group, per a report from the UK's MoD.
The location, located using surveillance, was thought to be containing munitions and bombs, the release indicated, and was located in mountainous terrain just above the ancient city of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a series of entry passages down to the site... initial indications are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian casualties in the strike conducted Saturday night and each participating jet returned safely, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as the so-called Islamic State - enforced extremist governance over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action shows British leadership, and resolve to stand shoulder to shoulder with our allies, to stamp out any resurgence of Daesh and their harmful and extremist ideologies in the region," UK Defence Secretary John Healey said.
RAF aircraft have conducted overwatch operations over Syria to "deter any attempted resurgence" of IS after its routing at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of British forces who took part in this mission for their skill and their courage," the Defence Secretary commented. "They were among numerous British troops deployed over the festive period. This action, to take out terrorist threats who pose a risk to our security, demonstrates how UK forces are prepared to act, all year round, protecting the UK within its borders and influential overseas."
During December, the United States armed forces executed what it termed a "large-scale strike" targeting Islamic State objectives in the country, following an attack resulted in the deaths of two US troops and a local interpreter in Palmyra.
The U.N. says Islamic State still has between 5,000 and 7,000 militants in both countries.
