European leaders arrive at a strategy summit on the continent's political frontline, where they are staging a show of unity in the face of Russia's aggression against Ukraine and Moldova. Four dozen leaders from across Europe are present in Bulboaca, Moldova, just 20 kilometres (12 miles) from the border with war-torn Ukraine. "I hope that the presence of so may leaders here, very close to Ukraine, at some kilometres of the borders, will send a strong message about the unity of many many States, not only European Union but others, on defending international order" says Josep Borrell, EU foreign policy chief, at his arrival.
