British Air Force Typhoon jets have conducted a mission with French aircraft in a joint strike against an hidden munitions depot in Syrian territory used by the Daesh militant organization, according to the British defence ministry.
The facility, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just above the historic site of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to target a number of access tunnels leading to the facility... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the attack conducted Saturday night and every plane involved returned safely, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - established jihadist rule over parts of both Syria and Iraq until 2019.
"This strike shows British leadership, and determination to work closely with allied nations, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary the minister said.
RAF aircraft have conducted overwatch operations over Syria to "prevent any efforts to regroup" of IS subsequent to its military defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I want to thank every member of British forces involved in this operation for their skill and their bravery," he added. "They were among thousands of British troops stationed over the holidays. This action, to take out dangerous terrorists who endanger our safety, shows how British military are prepared to act, all year round, protecting the UK within its borders and influential overseas."
In December, the US military carried out what it called a "massive strike" against Islamic State objectives in Syria, subsequent to an attack killed two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 fighters in both countries.
