RAF Typhoon FGR4s have conducted a mission with French aircraft in a combined operation on an subterranean weapons facility in Syria used by the IS group, as stated by the UK Ministry of Defence.
The facility, located using reconnaissance, was thought to be housing weapons and explosive materials, the announcement noted, and was positioned in hills just to the north of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to target a series of entry passages down to the facility... initial indications indicate the strike was effective," the ministry announced.
There was no evidence of any harm to civilians in the strike conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as ISIS - imposed jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and commitment to work closely with allied nations, to stamp out any re-emergence of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary John Healey said.
UK warplanes have conducted patrols over Syrian airspace to "prevent any efforts to regroup" of the group after its defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank every member of our armed forces involved in this mission for their skill and their bravery," the Defence Secretary commented. "They were part of numerous British personnel on duty over the festive period. This action, to eliminate terrorist threats who endanger our way of life, highlights how British military are prepared to act, all year round, ensuring Britain's security at home and strong abroad."
In December, the US military carried out what it called a "large-scale strike" targeting IS targets in the country, following an attack resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN says Islamic State still boasts roughly 5-7 thousand fighters in Iraq and Syria.
