Combined British-French Airstrike Strikes IS Arms Cache in the Syrian region

British Air Force Typhoon FGR4s have operated alongside French aircraft in a coordinated attack against an underground arms cache in Syrian territory used by the Islamic State group (IS), as stated by the UK Ministry of Defence.

The location, located using surveillance, was believed to be containing munitions and bombs, the statement said, and was situated in hills just above Palmyra in Syria's central region.

"The RAF jets used precision-guided Paveway IV munitions to hit a series of entry passages providing entry to the facility... early reports indicate the strike was effective," the ministry announced.

There was no indication of any civilian impact in the attack on Saturday evening and every plane involved made a safe return, the defence officials confirmed.

The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.

IS - referred to as ISIS - established militant control over parts of Syria and Iraq until 2019.

"This operation demonstrates British leadership, and commitment to operate in unison with our partners, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the minister stated.

British military aircraft have conducted patrols over Syria to "prevent any attempted comeback" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the ministry said.

"I want to thank all the members of British forces who took part in this operation for their skill and their courage," Healey added. "They were among a great many UK service members deployed over the festive period. This mission, to remove militants who endanger our security, demonstrates how UK forces are always on standby, continuously, protecting the UK domestically and strong abroad."

In December, the United States armed forces conducted what it described as a "major assault" against Daesh sites in Syria, following an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.

The U.N. estimates Islamic State still has roughly 5-7 thousand fighters in Syria and Iraq.
