World leaders gather in Munich to avert Russia-Ukraine war

Heavy fire in the east of Ukraine today has killed two soldiers, a reminder that the country has long been in a permanent state of war.

At the same time, there were increasingly stern words for President Putin from the world leaders gathered in Munich.

Ukraine's president was there to appeal for support, urging them to impose sanctions now before it is too late and warning that the world needs to learn the "terrible lessons from history".
