They agreed there remained a crucial window for diplomacy and for Russia to step back from its threats towards Ukraine."

Adding: "The leaders emphasised that any further incursion into Ukraine would result in a protracted crisis for Russia, with far-reaching damage for both Russia and the world.

The two leaders have said they will keep in close contact as the situation develops.
