“In general, as of Easter morning, we can say that the Russian army is trying to create a general impression of a ceasefire, but in some places it does not abandon individual attempts to advance and inflict losses on Ukraine,” Zelensky said in a post on social media.

Putin, hours before heading to an Orthodox Easter service late yesterday, announced the surprise one-day ceasefire, ordering his forces to “stop all military activity” along the frontline in the three-year-old war.

The gesture followed a US announcement that it could abandon peace talks within days unless Moscow and Kyiv showed they were serious about negotiating.

Fighting was to stop from 6pm Moscow time yesterday until midnight tonight, Putin said.

But Zelensky said there had been hundreds of instances of shelling yesterday evening.

Early today, Ukrainian forces reported 59 instances of shelling and five assault attempts along the frontline, he said.

“Russia must fully comply with the conditions of silence,” Zelensky said.

He reiterated that Kyiv was willing to extend the ceasefire for 30 days but said that if Russia kept fighting today, so would Ukraine.

“Ukraine will continue to act in a mirror manner,” he said.
