'North Korea is looking for trouble': Trump tweets extraordinary warning declaring that if China 'does not decide to help we will solve the problem without them'

The US President (top right) wrote the message on Twitter after revealing he had urged his Chinese counterpart Xi Jinping to pressure Pyongyang in to stopping its nuclear programme. His warning came as Russia admitted it is 'extremely worried' the US will attack Kim Jong-Un (bottom right) after North Korea warned it has US bases 'in its nuclear sights'. Pyongyang had earlier threatened 'catastrophic consequences' after Donald Trump sent an armada of warships to the Korean Peninsula (left). At the same time, China has moved 150,000 troops to its border to deal with a possible influx of North Korean refugees amid fears Trump may strike Kim Jong-un following the surprise US missile attack on Syria last week.
