Royal Air Force Typhoon fighter aircraft have operated alongside French warplanes in a joint strike targeting an hidden munitions depot in Syria employed by the Islamic State group (IS), per a report from the UK's MoD.
The site, located using surveillance, was thought to be containing munitions and bombs, the release indicated, and was located in mountains just to the north of the historic site of Palmyra in central Syria.
"Our aircraft utilized precision-guided Paveway IV munitions to target a number of approach shafts down to the facility... early reports indicate the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
IS - referred to as ISIS - imposed jihadist rule over significant areas in Iraq and Syria until 2019.
"This action shows British leadership, and commitment to stand shoulder to shoulder with our allies, to eliminate any resurgence of IS and their violent and radical beliefs in the area," UK Defence Secretary the Defence Secretary said.
UK warplanes have conducted patrols over Syria to "deter any attempted comeback" of IS after its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I extend gratitude to all the members of the UK armed forces involved in this operation for their professionalism and their courage," he added. "They were among numerous British personnel stationed over the holidays. This operation, to remove terrorist threats who threaten our way of life, highlights how British military are ready to step up, all year round, protecting the UK at home and powerful internationally."
Last December, the American forces conducted what it called a "major assault" on Islamic State objectives in the country, following an assault claimed the lives of two American soldiers and a civilian interpreter in Palmyra.
The UN estimates IS still maintains between 5,000 and 7,000 militants in both countries.
