An Orthodox Easter truce agreed by Russia and Ukraine came into force on Saturday afternoon but 38 minutes later we heard air raid sirens in Kharkiv region, northeastern Ukraine.

Since then, officials and military have recorded multiple ceasefire violations along the frontline, although no long-range missile or drone strikes.

The pause in fighting is supposed to last until Easter Monday to give people a much-needed rest, more than four years after Russia launched its full-scale invasion.

"Easter should be a time of safety, a time of peace," Ukraine's President Volodymyr Zelensky wrote on X, warning that Ukrainian forces would respond "strictly in kind" to any actions by Moscow.

Expectations and trust are very low here.
