France has two months to deliver first Mistral ship to Russia

Russia on Friday warned France of "serious" consequences unless Paris delivers by the end of this month a Mistral-class assault warship whose handover has been delayed by concerns over Moscow's role in the Ukraine crisis, a report said.

"We are preparing for different scenarios. We are waiting until the end of the month, then we will lodge serious claims," the state news agency RIA Novosti quoted an anonymous high-ranking Moscow source as saying.

The Moscow source said on Friday experts were currently gauging the damage sustained by Russia and it would be made public.

"This amount will not be secret," the source was quoted as saying by RIA Novosti.
