French President Emmanuel Macron blasted Russia on Sunday for its missile attack on the Ukrainian city of Sumy and called for "strong measures" to impose a "ceasefire on Russia."

"Everyone knows: this war was initiated by Russia alone. And today, it is clear that Russia alone chooses to continue it — with blatant disregard for human lives, international law, and the diplomatic efforts of [US] President [Donald] Trump," Macron said in a post on X. "Strong measures are needed to impose a ceasefire on Russia. France is working tirelessly toward this goal, alongside its partners," he added.

Earlier, Acting Sumy Mayor Artem Kobzar announced that more than 30 civilians were killed in Moscow's ballistic missile attack on the city.
