Foreign Secretary Philip Hammond has said "we're not holding our breath" for a breakthrough in the peace talks between Russia and Ukraine taking place in Minsk today.
Speaking on the sidelines of the Nato summit in Wales, he said it was important not to be distracted by "noises of a ceasefire" until there are changes on the ground in Ukraine.
He added: "If there is an agreement later today, if ... we see Russian troops going back into Russia, the supply of equipment to the separatists ending, the shelling and rocket fire from across the Russian border into Ukraine ending, then of course we can then talk about lifting sanctions off."
Angus Raffle, 8, says his surprise meeting with the President at Stonehenge was "awesome". His mother says she "squealed like a teenager".
The language has been ramped up at this Nato summit, yet caution appears the order of the day after the mistakes of recent history.
