British Air Force Typhoon FGR4s have operated alongside French aircraft in a combined operation against an subterranean weapons facility in Syria operated by the IS group, per a report from the UK's MoD.
The facility, pinpointed through surveillance, was believed to be storing arms and explosives, the announcement noted, and was located in hills just to the north of Palmyra in Syria's central region.
"Our aircraft utilized precision-guided Paveway IV munitions to target a series of entry passages leading to the depot... initial indications are that the strike was effective," the MoD said.
There was no evidence of any civilian casualties in the strike late on Saturday and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
Daesh - also known as Daesh - imposed jihadist rule over parts of both Syria and Iraq before its territorial defeat in 2019.
"This operation underscores the UK's leading role, and commitment to operate in unison with allied nations, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "prevent any attempted comeback" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank all the members of British forces involved in this mission for their skill and their valour," the Defence Secretary said. "Including them were numerous British personnel deployed over the festive period. This operation, to remove terrorist threats who threaten our security, shows how British military are prepared to act, all year round, keeping Britain secure domestically and influential overseas."
During December, the US military executed what it described as a "major assault" on Islamic State objectives in the country, subsequent to an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN estimates IS still boasts roughly 5-7 thousand combatants in both countries.
