Russia has launched its heaviest drone attack on Ukraine since the start of the war in 2022, the Ukrainian military has said.
A total of 273 exploding drones were reportedly fired across the Kyiv, Dnipropetrovsk and Donetsk regions between Saturday night and Sunday morning.
Some 88 were intercepted and 128 "lost", having been electronically jammed, Ukraine's air force said.
It passes the previous record of 267 drones on the eve of the war's third anniversary earlier this year.
In Kyiv, a 28-year-old woman was killed, and three people, including a four-year-old child were injured, according to regional governor Mykola Kalashnyk.
Just outside the city, firefighters fought to control flames at business premises destroyed by drone attacks. Russia has not commented.
It comes ahead of a planned phone call between US President Donald Trump and his Russian counterpart Vladimir Putin.
Mr Trump has promised to speak to Mr Putin and then President Volodymyr Zelenskyy on Monday about "ending the war" after the first direct talks between their two countries failed to yield a ceasefire this week.
Mr Putin snubbed Mr Zelenskyy's offer of face-to-face talks in Turkey.
A source from the Ukrainian negotiation team told Sky News that Russia threatened "eternal war" during talks between officials.
Kremlin representatives are also reported to have threatened that Ukraine may lose "more than just loved ones" while at the negotiating table.
Talks did bring promise of the largest ever prisoner swap between the two nations - involving 1,000 prisoners of war on each side.
Ukraine's military intelligence chief said he hoped it would take place over the next week.
