Despite efforts to find a diplomatic solution, Russia’s Foreign Minister Sergei Lavrov has said there is still no deal between Washington and Moscow over how to solve the crisis in Ukraine.

Speaking in Rome after meeting his US counterpart, Secretary of State John Kerry, Lavrov said the White House’s order to freeze assets and block visas of Russians responsible for an incursion into Crimea was not constructive.

The two men met briefly on the sidelines of a conference about Libya for the second day running, having held talks in Paris on Wednesday.
