London, UK (BBN)-RAF jets have carried out their second set of air strikes in Syria since MPs backed military action against so-called Islamic State in the country.
It is understood the targets were oil fields again, and the mission involved two Tornados and, for the first time, two Typhoons, reports BBC.
Four Tornado jets launched the first air strikes on Thursday, hitting the Omar oil fields in eastern Syria.
They came just hours after MPs gave their backing for military action.
Six Tornados flew to RAF Akrotiri in Cyprus on Thursday to join the operation against IS, which the government refers to as Daesh and is also referred to as Isis and Isil.
The Ministry of Defence said the deployment of the Typhoons plus an extra two Tornados offered a significant increase in strike capacity to both the RAF and the wider coalition air campaign.
