Russia and Iran warn Trump they will retaliate militarily against US if it crosses their 'red line' again

Russia and Iran would retaliate with military action if more airstrikes are launched against Syria. Both countries  said the US President crossed a 'red line' with his surprise missile attack on Bashar al-Assad's forces.

'From now on we will respond with force to any breach of red lines and America knows our ability to respond well,' the military chiefs said in a joint statement with militant group Hezbollah.


The Russian Embassy in London on Sunday night said there could be real war if Moscow is presented with an ultimatum over Syria.

But UK Foreign Secretary Boris Johnson will lead a push on Monday for Russia to face tough new sanctions unless it withdraws its support for Assad.
