RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a coordinated attack against an underground arms cache in Syrian territory used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was situated in hills just above the historic site of Palmyra in the heart of Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a series of entry passages down to the facility... early reports are that the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation late on Saturday and all the aircraft returned safely, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.

"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our allies, to eradicate any re-emergence of Daesh and their violent and radical beliefs in the region," Britain's Defence Chief the minister said.
RAF aircraft have performed surveillance missions over Syria to "forestall any attempted comeback" of IS subsequent to its routing at the climactic battle in Baghuz in the year 2019, the authorities noted.
