As Russian strikes follow the EU's support for Kyiv, NATO warns of a long conflict in Ukraine

The conflict in Ukraine might linger for years, according to NATO's top officer, as Russia ramped up its attacks after the European Union approved Kyiv as a candidate for membership.

According to Germany's Bild am Sonntag newspaper, Jens Stoltenberg claimed that providing state-of-the-art weaponry to Ukrainian troops would increase the chances of releasing the country's eastern territory of Donbas from Russian control.
