At least six people have died after Russia unleashed missile and drone barrage attacks across parts of Ukraine. Russia unleashed the wave of intense bombardment and bombed a blood transfusion centre after vowing to retaliate for a Ukrainian hit on Russian tankers in the Black Sea. Moscow’s second-largest airport also briefly suspended flights on Sunday morning following what the Kremlin said was a foiled Ukrainian drone attack. Ukrainian authorities have not commented on either raid. The Ukrainian air force said on Sunday that Russian forces had in total launched 70 Iranian-made Shahed drones, as well as cruise and hypersonic missiles from aircraft over the Caspian Sea. Russian shelling in the northern region of Kharkiv also killed three people. It comes as senior officials from some 40 countries, including the US, China and India took part in talks in Saudi Arabia that Kyiv and its allies hope will lead to an agreement on key principles for a peaceful end to Russia’s war in Ukraine. Russia did not attend the meeting.
