Western allies provided advance warning about only one of two overnight attacks, says Ukrainian air force. Russia fired drones and missiles at 11 regions on Monday, leaving 550,000 households without power. A 21-year-old woman died in Kyiv. Ukraine only shot down four missiles as tensions with Washington grew over sanctions.

Western allies provided advance warning about only one of two overnight attacks, says Ukrainian air force

Ukraine received intelligence from western partners about just one of two Russian ballistic missile attacks overnight into Monday, as relations between Kyiv and Washington have sharply deteriorated in recent days.

More than 200 drones and several "Banderol" cruise missiles targeted energy facilities in 11 regions, leading to power outages for about 550,000 households, according to President Volodymyr Zelenskyy and a report by Ukraine's air force.

Kyiv residents heard explosions in two distinct waves on Sunday night. Yurii Ihnat, spokesperson for the Ukrainian Air Force, said there had been no warning about the first wave of ballistic missiles, but said the country's air defence and authorities had received warnings about the second one.

Ukraine's air force said it had only managed to shoot down four missiles overnight.

Russia's defence ministry said it had fired drones and ground-launched missiles at what it claimed were defence infrastructure sites in Kyiv, as well as a data centre. The ministry said it also struck a ship approaching the port of Odesa that it claimed was carrying military and dual-use cargo.

A 21-year-old woman died in the attack on Kyiv, according to Ukraine's emergency services. The Datagroup company confirmed that one of its data centres had been destroyed in Kyiv overnight. A metro station on the city's left bank was also damaged in the attack.

Zelenskyy's dispute with Donald Trump over the US president's decision to relax economic sanctions on Russia deepened on Monday.

"When deliveries of missiles for Ukraine's air defence are blocked while Russia is granted relief or delays in sanctions, this is, unfortunately, a denial of reality on the part of our partners," Zelenskyy said.

The statement came hours after Trump posted on his Truth Social platform that the Ukrainian president did not want "to end this war".

Zelenskyy had said on Sunday that intelligence sharing from the US had resumed after a brief pause. Ukraine is particularly reliant on US satellites to detect the launch of ballistic missiles able to reach major Ukrainian cities in mere minutes.

Kyiv has also accused Washington of introducing speed limits to the Starlink communication systems. The satellite-based system operated by Elon Musk's SpaceX is ubiquitous in Ukraine's armed forces, and allows Ukrainian forces to fly drones targeting Russian positions and vehicles as well as drones.

US secretary of state Marco Rubio denied on Sunday that Washington had introduced restrictions. But Zelenskyy told reporters over the weekend that experiments had proved that only drones flying inside Ukraine were restricted to a speed of 160kph. Similar drones flown in the EU had no such restrictions, he said.
