Russia is waging a “targeted grey-zone campaign” against Europe, including airspace violations, sabotage and cyber attacks that will only escalate if the Kremlin is not challenged, the European Union’s top official has warned.

European Commission President Ursula von der Leyen said that in just two weeks, fighter jets had breached Estonia’s airspace, while drones overflew military bases and critical infrastructure sites in Belgium, Denmark, Germany, Poland and Romania.
