The European Union is set to launch a first operation in a new propaganda war with Russia within days of EU leaders giving formal approval to the campaign at a summit Thursday.

Officials said that a dozen public relations and communications experts will start work by the end of March in Brussels with a brief to counter what the EU says is deliberate misinformation coordinated by the Kremlin over Moscow's role and aims in Ukraine and elsewhere in Europe.

It is the first stage of a plan that leaders want EU foreign policy chief Federica Mogherini to finalize by June, which may include efforts to produce and share Russian-language broadcast programming, notably for ethnic Russians in former Soviet states.
