British fighter jets destroyed two cells of Islamic state fighters in a bombing raid on caves in northern Iraq.
RAF Typhoons launched laser-guided missiles into a network of extremist hideouts near the city of Bayji, 130 miles north of Baghdad.
Defense chiefs say they carried out the strike to stamp out an ISIS insurgency in the region.
A Defense Ministry spokesman said: “Royal Air Force aircraft have continued their regular armed reconnaissance missions to support the continued work of the Iraqi security forces and prevent a resurgence of the Daesh terrorist movement in their country.”
The British armed forces launched an operation last Sunday after coalition surveillance planes discovered ISIS fighters hiding in two caves a mile and a half apart.
A pair of Typhoon FGR4s were deployed and carried out an overpass before two guided bombs were fired against each group – obliterating the “terrorist threat”.
The Defense Department spokesman said his plane had “carefully” checked the area around the caves “for signs of civilians at risk” prior to the strike.
“All four bombs hit their targets and the strike was rated as a success in eliminating the terrorist threat,” the statement said.
This week, American air strikes reportedly killed the leading ISIS leader in Iraq.
Jabbar Salman Ali Farhan al-Issawi, 43, known as Abu Yasser, was killed near the northern Iraqi city of Kirkuk on Wednesday.
According to terror experts, Al-Issawi coordinated the group’s operations in Iraq.
The jihadist group no longer holds any territory in Iraq but has continued to carry out deadly attacks.
The bombing in Iraq comes after a British SAS sniper killed five terrorists in Syria with a single shot and from more than half a mile away.
The unidentified SAS sergeant picked up a jihad suicide bomber from a distance of 3,000 feet while speaking to the camera. The resulting explosion also knocked down four more.
The 20-year-old veteran used the army’s most powerful weapon during a killing or conquest mission against the Islamic State in November.
