A day after President Trump signaled that Ukraine wasn’t a top priority, and following Russia’s deadliest attack on Kyiv in weeks, Ukrainian President Volodymyr Zelensky left a summit of the Group of Seven industrial nations without the support he had hoped to rally.

Ahead of a meeting of the Group of Seven, Trump told reporters that ousting Russia from the talks in 2014 was a "very big mistake," adding that there would not be a conflict between Russia and Ukraine if President Vladimir Putin was still welcome at the summit.

No 10 says G7 allies back the measures - but Donald Trump indicates the US will not impose more sanctions now.

U.S. president shrugs off EU and U.K. call for more action over Ukraine war, telling Europe: “Let’s see them do it first.”

As G7 leaders converge on Kananaskis in the Canadian Rockies this weekend, the prospect of decisively tougher sanctions on Russia will loom large.
