NATO Secretary-General Jens Stoltenberg is visiting Ukraine for the first time since Russia launched its full-scale invasion more than a year ago, an alliance official said Thursday.

“The NATO secretary-general is in Ukraine. We will release more information as soon as possible,” said an alliance official, who asked not to be identified in line with NATO procedures. Pictures of Stoltenberg apparently paying tribute to fallen Ukrainian soldiers in Kyiv’s St Michael’s Square were published by local media.
