Prime minister made comment en route to Washington where he is having talks with Joe Biden during a two-day visit
Rishi Sunak has said if Russia was responsible for the destruction of a dam in Ukraine, it would be a “new low” for Moscow in the invasion.
Speaking to reporters on board his official plane to Washington, where he is to hold pre-planned talks with the US president, Joe Biden, Sunak said the UK cannot yet know for certain who was to blame for the collapse of a vast dam on the Dnipro River that Kyiv said was blown up by Russian forces to hamper a Ukrainian military push.
