With relations between Russia and the West at post-Cold War lows and deteriorating fast, Royal Air Force (RAF) pilots have been given the go-ahead to shoot down Russian military jets when flying missions over Syria and Iraq, if they are endangered by them. The development comes with warnings that the UK and Russia are now "one step closer" to being at war, according to the Sunday Times.

While the RAF's Tornado pilots have been instructed to avoid contact with Russian aircraft while engaged in missions for Operation Shader, the codename for the RAF's anti-Isis work in Iraq and Syria, their aircraft have been armed with air-to-air missiles and the pilots have been given the green light to defend themselves if they are threatened by Russian pilots.
