The Islamic State group - also known as Daesh - imposed jihadist rule over parts of both Syria and Iraq until 2019.
"This strike demonstrates British leadership, and resolve to operate in unison with allied nations, to eradicate any revival of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the minister remarked.
British military aircraft have conducted patrols over Syria to "forestall any efforts to regroup" of Islamic State after its defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to every member of British forces involved in this strike for their professionalism and their courage," the Defence Secretary commented.
