Russian military aircraft repeatedly crossed over into Ukraine's airspace overnight, Ukrainian Prime Minister Arseny Yatseniuk said on a visit to the Italian capital.
"Russian military aircraft today at night crossed and violated Ukrainian airspace seven times. The only reason is to provoke Ukraine ... and to accuse Ukraine of waging war against Russia," Yatseniuk, who was speaking English, told reporters in Rome.
