Russia on Monday (May 4, 2026) declared a unilateral ceasefire with Ukraine between May 8 and May 9, when Moscow marks its annual World War II Victory Day commemorations, and threatened a “massive missile strike” on Kyiv if Ukraine violated it.
Ukraine responded by declaring a truce of its own between May 5 and May 6, saying it was “not serious” to expect it to observe a ceasefire during a Russian military holiday.
