Romania's top court on Thursday ordered a recount of votes in the first round of the presidential election and the country's top security body warned Romania was a key target for hostile actions from Russia after a shock result in the ballot.

The recount was ordered by Romania's Consitutional Court. Far-right populist Calin Georgescu won the first round of the presidential election and was set to go against centrist Elena Lasconi in a December runoff.

A top Romanian court has asked the official electoral authority to recount and verify all of the ballots cast in the first round of the presidential election.
