Russia unleashed another missile and drone blitz of civilian areas in Ukraine, killing at least seven people, officials said Tuesday, as Ukrainian President Volodymyr Zelenskyy scrambled to ensure more American and European help during a visit to Norway.

U.S. envoy Steve Witkoff, who along with Jared Kushner has tried without success to steer Russia and Ukraine toward a settlement and end the war, was also expected in Oslo, the Norwegian government said.

Kushner, who is U.S. President Donald Trump's son-in-law, will attend the meeting by videoconference, it said.
