"The European Union condemns and does not recognise the illegal annexation of Crimea and Sevastopol by the Russian Federation. We continue to be unwavering in our support for the territorial integrity and sovereignty of Ukraine," Mogherini said.
"Any actions that could lead to a further escalation of the conflict must be avoided by all sides; a peaceful resolution of the conflict is the only possible solution. This includes eastern Ukraine, where we urge all parties to fully engage in the complete implementation of the Minsk agreements," she added.
"The European Union and its Member States will continuously assess the situation, including at the level of the Political and Security Committee next Wednesday," the EU High Representative said.
