Ukraine crisis: Leaked US phone call appears online

An apparently bugged phone conversation in which a senior US diplomat disparages the EU over the Ukraine crisis has been posted online.

A voice resembling that of Assistant Secretary of State Victoria Nuland refers to the EU using a graphic swear word, in a conversation apparently with the US ambassador to Ukraine.

The US said Ms Nuland had "apologised for these reported comments".

The EU and US are involved in talks to end months of unrest in Ukraine.
