Ukraine war latest: Putin ally issues warning over nuclear treaty - as Kremlin gives update on peace talks

Volodymyr Zelenskyy says there were no new targeted strikes by Russian missiles or Shahed drones on Ukraine's energy infrastructure over the past 24 hours.

However, in an online post today, he adds that there have been Russian attacks on energy facilities in frontline regions.

"The Russian army remains focused on terror against our logistics - primarily railway infrastructure," Zelenskyy says.

"In particular, there were strikes in the Dnipro region and in Zaporizhzhia, specifically targeting railway facilities." 

Zelenskyy says he held a coordination call to discuss the situation in Ukraine, adding that "more than 200 buildings" in Kyiv are still without heating.

When asked whether Russia's attacks on Ukraine's energy infrastructure amounted to war crimes, our military analyst Michael Clarke last week said it depended on the intention. 

"In other words, it's automatically a war crime to try to make civilians suffer in a war," he said in his weekly live Q&A last week.

"It's a war crime if the intention is anti-civilian, which in this case it certainly is, I don't think the Russians could possibly defend themselves on the basis that this was in any way military related."

Troops from the Ukrainian Armed Forces have been pictured returning from positions on the frontline.

The soldiers from the 93rd Mechanized Brigade spent 50 days on the battlefield amid Russia's attack on Ukraine.

Russia remains "open to negotiations" on Ukraine, but they should take place in Moscow, Kremlin spokesperson Dmitry Peskov says.

When asked about progress on a deal with Ukraine, Peskov says it's a "complex multi-faceted process".

"On some issues, we have made progress because there have been discussions and talks. On some issues, it's easier to find common ground," he adds.

"There are issues where it's harder to find common ground. There can't be any progress there yet."

On whether negotiations between the Russian president and Zelenskyy could take place on neutral territory, Peskov says, "Putin said they are possible in Moscow".

The spokesperson also says French President Emmanuel Macron's call for dialogue with Moscow "is sensible, and we share it".

Volodymyr Zelenskyy has confirmed trilateral talks between Ukraine, the US and Russia would go ahead on Wednesday in Abu Dhabi.

In remarks over the weekend, Zelenskyy said: "There is already an agreement on a meeting - a trilateral meeting - at the appropriate level."

"This meeting will take place next week, as planned, on Wednesday and Thursday in the Emirates, like last time," he added.

We've got an update on Russian shelling in Ukraine overnight, with the country's national police reporting that three people were injured in the southern Kherson region.

A woman aged 59 "came under enemy shelling" and was taken to hospital with head injuries and shrapnel wounds in the leg, police said.

Two pensioners were injured by shelling that hit their apartments in residential areas of the Dniprovskyi district, they added.

A 79-year-old woman and a 75-year-old man suffered mine-explosive injuries.

Volodymyr Zelenskyy has called a Russia bus attack that killed 12 people yesterday afternoon a "demonstrative crime". 

Seventeen others were injured when a bus carrying mineworkers in the southern city of Dnipro was hit by a drone.

Zelenskyy said it showed Russia was responsible for escalation before calling for the "evil" to be stopped.

Dmitry Medvedev has also warned that the world should be alarmed if a nuclear arms reduction treaty between Russia and the US expires without replacement.

If that were to happen, the former Russian president said, countries with the biggest nuclear capabilities would have no limits for the first time since the early 1970s.

"I don't want to say that this immediately means a catastrophe and a nuclear war will begin, but it should still alarm everyone," Medvedev said.

Arms control treaties played a crucial role, he added, not just in restricting the number of warheads, but also in verifying intentions to ensure a level of trust between nuclear powers.

For context: The New START treaty was signed on 8 April 2010 and followed several separate treaties between the US and Russia.

It followed the first treaty between the US and the Soviet Union, signed in 1991 and first drafted in June 1982. 

A proposal by European countries to station NATO-member troops in Ukraine for security and a peace deal is unacceptable, a key Putin ally has said.

Dmitry Medvedev, deputy chairman of Russia's Security Council and a former president of the country, added: "What kind of guarantee can we talk about if a foreign contingent of unfriendly NATO member states is stationed on the territory of such a state." 

Medvedev said Russia's terms for ending the conflict were unchanged from 2024 when Vladimir Putin set them out in a speech at the foreign ministry.

He added that Moscow was "not interested in a global conflict".

"We're not crazy," he said.

Good morning and welcome back to our live coverage of the war in Ukraine.

We'll be starting the day with former Russian president Dmitry Medvedev, who says plans to have NATO-member troops in Ukraine as part of a peace deal are unacceptable for Russia.

We'll have all more on that soon, along with all the latest updates from the battlefield and negotiations to end the fighting on this live page. Stay with us.
