British Air Force Typhoon FGR4s have joined forces with French warplanes in a joint strike on an hidden munitions depot in Syria used by the Islamic State group (IS), per a report from the UK Ministry of Defence.
The facility, pinpointed through intelligence, was assessed as containing munitions and bombs, the statement said, and was situated in hills just north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft utilized precision-guided Paveway IV munitions to target a series of approach shafts down to the depot... preliminary assessments are that the target was engaged successfully," the MoD said.
There was no indication of any civilian impact in the operation on Saturday evening and every plane involved returned safely, the MoD added.
The British jets were assisted by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - imposed extremist governance over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action shows the UK's leading role, and resolve to work closely with allied nations, to eradicate any revival of IS and their dangerous and violent ideologies in the region," UK Defence Secretary the minister said.
British military aircraft have performed overwatch operations over Syrian airspace to "prevent any attempted resurgence" of IS after its military defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I must thank all the members of British forces participating in this mission for their skill and their bravery," the Defence Secretary said. "They were part of numerous British personnel stationed over Christmas and New Year. This operation, to remove terrorist threats who pose a risk to our security, demonstrates how UK forces are ready to step up, all year round, keeping Britain secure within its borders and powerful internationally."
Last December, the US military carried out what it termed a "major assault" against Daesh sites in Syria, following an ambush killed two US troops and a civilian linguist in the Palmyra area.
The United Nations says Islamic State still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
