David Cameron has said the Malaysian Airlines crash in east Ukraine is a "defining moment" for Russia

 Some 298 people died, including 10 Britons, when flight MH17 crashed in a pro-Russian rebel-held area last week. The PM said Moscow was fuelling the Ukraine conflict by arming the rebels, who are accused of downing the jet. He said it was unlikely the plane was shot deliberately - but warned of "hard-hitting" sanctions if Moscow did not change course on Ukraine. Mr Cameron said there was "anger" at what had happened and urged Moscow to stop training separatists and supplying them with weapons. The UK is set to push for increased sanctions against Russia at a meeting of EU foreign ministers on Tuesday.
