Ukraine and Russia have renewed drone strikes after a 32-hour ceasefire for Orthodox Easter expired at midnight on Sunday.
Russian President Vladimir Putin announced the truce on Thursday and ordered Russian forces to halt operations from 4pm local time on Saturday until the end of Sunday.
Ukrainian President Volodymyr Zelensky said his forces would observe the ceasefire as well.
The pause ended on Monday morning with both sides reporting fresh drone activity.
Ukrainian officials said Russian forces carried out strikes with attack drones and first-person-view models along the front lines.
Russian authorities reported Ukrainian drone attacks on border areas in Kursk and Belgorod regions that injured civilians.
Meanwhile, the two governments traded accusations of widespread breaches during the truce itself.
Ukraine’s General Staff recorded more than 2,200 violations by Russian forces by early Sunday, most of them involving artillery shelling and drone strikes.
Russia’s defence ministry listed nearly 2,000 violations by Ukrainian units in the same period.
However, neither side launched long-range missiles or guided bombs while the ceasefire lasted.
Artillery fire and short-range drone attacks continued at lower levels in several sectors, according to officers on the ground.
The truce had aimed to give Orthodox Christians a break from fighting during the holiday.
In the event, fighting never fully stopped.
Ukrainian troops near Donetsk and Zaporizhzhia reported Russian drones overhead even after the 4pm start time on Saturday.
Russian border governors described Ukrainian drone incursions that damaged buildings and hurt residents.
As the ceasefire ended, both militaries returned to normal operations.
Front-line units on each side say they responded to attacks with fire of their own.
The exchange of accusations shows how quickly the brief pause gave way to the same pattern of strikes that has marked the conflict for more than four years.
No immediate casualty figures emerged from the first hours after the truce expired.
Officials in Kyiv and Moscow continue to monitor developments along the 1,000-kilometre front.
