RAF jets have carried out their second round of air strikes on Isis targets in Syria since MPs voted to extend Britain’s bombing campaign.
Oil fields controlled by the extremist group were targeted for a second time, using two Typhoons and two Tornados, the BBC reported.
The first operations in Syria were launched on Thursday, when four planes hit the Omar oil fields in the east of the country.
Michael Fallon, the Defence Secretary, said Isis derives “a huge part of its revenue” from sales.
He said Paveway guided bombs were used to hit wellheads in an area where there was “simply infrastructure” and no civilians.
“The Prime Minister has been pretty clear that this is going to be a long campaign to ensure that Daesh are thrown out of Iraq and that they are degraded and degraded in eastern Syria,” Mr Fallon continued.
“This is not going to be quick but it wasn’t right to simply leave it to other air forces.”
Extra fighter jets have been sent to the UK’s Cyprus base, RAF Akrotiri, to launch bombing and reconnaissance missions over Syria and continue Operation Shader in Iraq, where Britain is providing support to Iraqi forces at the government’s request.
The Ministry of Defence said Tornado GR4s were involved in fighting against Isis militants near the city of Ramadi on Friday, adding: “A terrorist sniper team opened fire from a compound on Iraqi troops, but was silenced by a direct hit from a Paveway IV guided bomb.”
MPs supported the Government’s proposals for intervention in Syria by 397 votes to 223 after a 10-hour debate in the House of Commons on Wednesday.
