UPDATE 1907 GMT:

Three civilians have been killed and 20 injured by a Russian drone strike on a bus in the Sumy region in northeast Ukraine.

The Russians attacked near the village of Yunakivka, around 8 km (5 miles) from the border.

UPDATE 1433 GMT:

Following Ukraine’s drone attacks early Sunday, Russia canceled today’s annual Navy Day parade in St. Petersburg for the first time.

Kremlin spokesperson Dmitry Peskov said the cancellation was “for security reasons”. Vladimir Putin had reportedly traveled to the city.

UPDATE 1241 GMT:

US-German software company Auterion is sending 33,000 AI drone “strike kits” to Ukraine before the end of 2025 under a contract with the Pentagon, helping Kyiv repel mass Russian attacks.

Auterion chief executive Lorenz Meier said the company’s software is already being used in Ukrainian drones, but the new commitment is “10 times in scale”.

UPDATE 1008 GMT:

Writing for the Financial Times, Simon Kuper reports on Russia’s “War Crimes in Real Time” in Ukraine.

Oleksandra Matviichuk of the Center for Civil Liberties, which won the Nobel Peace Prize in 2022, says that “the international order, based on the UN charter and international law, is collapsing” and probably is not coming back. So when asked how to stop Russian war crimes, she says, “Give Ukraine Weapons”.

“It’s weird to hear [that] from the human rights lawyer,” she acknowledges.

The Ukraine Prosecutor General’s Office is investigating 177,000 suspected war crimes, possibly the highest level in the world alongside Israel’s mass killing in Gaza.

Mirjana Spoljaric Egger, President of the International Committee of the Red Cross links the two cases:

The level of destruction in Gaza is the highest level of destruction when it comes to interpreting what is allowed under the Geneva Convention. What we see in Gaza sends a signal. Warring parties look at Gaza and say, “Look, it’s possible to do that. And there’s no intervention.”

UPDATE 0959 GMT:

At least six civilians have been killed and at least 20 injured by Russian attacks across Ukraine over the past 24 hours.

Air defenses downed 78 of 83 drones fired by Russia overnight.

Two civilians were slain and two injured in the Sumy region in northeast Ukraine. Administrative buildings, markets, and houses were damaged.

Two people were murdered and at least wounded in the Donetsk region in the east.

In the Zaporizhzhia region in the south, two civilians were found dead under the rubble of a destroyed house.

Casualties were also reported in the Kherson and Dnipropetrovsk regions.

UPDATE 0719 GMT:

Officials say Germany has completed the delivery of three US-made Patriot air defense systems to Ukraine.

Earlier this month, Donald Trump said he would approve the sale of the Patriot systems to NATO members who would then send them to Kyiv.

On Thursday, Ukraine President Volodymyr Zelensky said he has asked partners for 10 systems and had been promised three.

ORIGINAL ENTRY: Ukraine’s drones have struck facilities inside Russia which are supporting Moscow’s 41-month full-scale invasion.

Among the sites hit on Saturday and into Sunday were the Signal radio and electronic warfare plant in the Stavropol region and railway power supply in the Volgograd region.

Two facilities at the Signal plant in the city of Stavropol, around 540 km (335 miles) from the Ukrainian border, were damaged. The plant is one of Russia’s leading producers of electronic warfare equipment, including radar, radio navigation components, and remote control radio systems.

Signal has been sanctioned by the European Union, the US, Ukraine, and Japan. Its equipment is used by Russian warplanes striking Ukrainian civilians as well as positions on the frontline.

An official from Ukraine’s State security security SBU said, “Each such attack stops production processes and reduces the enemy’s military potential. This work will continue.”

Early Sunday, Russia’s civil aviation authority shut airport of the city of Volgograd, around 900 km (550 miles) from the border with a population of more than 1 million. Flights were also delayed in St. Petersburg and Kaluga.

Moscow Governor Oleg Melnichenko said drones again targeted the region, including an industrial facility southeast of the Russian capital.

The Russian Defense Ministry claimed 99 drones were intercepted overnight.
