"The RAF jets employed precision-guided Paveway IV munitions to strike a several entry passages down to the site... early reports are that the objective was successfully hit," the ministry announced.

The Islamic State group - alternatively referred to as the so-called Islamic State - imposed jihadist rule over parts of both Syria and Iraq until 2019.
"This action demonstrates the UK's leading role, and determination to stand shoulder to shoulder with our allies, to eradicate any resurgence of IS and their violent and radical beliefs in the region," Britain's Defence Chief John Healey stated.
British military aircraft have performed patrols over Syrian airspace to "deter any efforts to regroup" of the group after its routing at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank every member of the UK armed forces involved in this operation for their expertise and their courage," he said. "Including them were numerous UK service members stationed over the festive period. This mission, to eliminate militants who endanger our security, highlights how our armed forces are ready to step up, throughout the year, keeping Britain secure domestically and influential overseas."
In December, the US military carried out what it called a "massive strike" against IS targets in the country, subsequent to an assault resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations says Islamic State still boasts roughly 5-7 thousand militants in Syria and Iraq.
