Royal Air Force Typhoons have scrambled twice in the same day to intercept Russian aircraft near Estonian airspace.
The British jets first intercepted a Russian military transport aircraft before later intercepting two Russian Flanker fighters and another military transport aircraft on Tuesday.
The Ministry of Defence said it was a routine mission as part of the UK's contribution to NATO enhanced Air Policing (eAP).
It is also the tenth and 11th Quick Reaction Alert (QRA) scramble and intercept respectively since the RAF took over eAP from the German Air Force on 3 May 2019 as part of Baltic Air Policing.
The Royal Air Force is deployed on Operation Azotize in Estonia in support of Baltic Air Policing.
The order to deploy was given by then-Defence Secretary Gavin Williamson, who in February confirmed the UK would be upping its contribution to NATO’s Enhanced Forward Presence.
It is the third time that Typhoons have been out to Estonia - the first was in 2015 and then again the following year.
