A Russian drone strike killed three people waiting at a bus stop in southeastern Ukraine on Sunday, an official said, as Keir Starmer hosts the leaders of Ukraine, France and Germany for talks on ongoing support for Kyiv.

Another person was wounded in the drone attack in Balabyne in Ukraine's southern Zaporizhzhia region, the head of the regional military administration, Ivan Fedorov, wrote on his Telegram channel.

Elsewhere, a Ukrainian attack killed one man and injured a woman in Russia's Kursk region, local Gov. Alexander Khinshtein said.

The Ukrainian president wrote on X on Sunday: “Today, the Russians again struck the special territory around the Chornobyl Nuclear Power Plant.

“A ‘shahed’ hit one of the buildings of the Centralized Spent Fuel Storage Facility. An extremely critical infrastructure facility – and an extremely vile Russian strike.

“The Ministry of Foreign Affairs of Ukraine, the Ministry of Energy, and all our services are already working to ensure that each of our partners knows what has happened. Russia deliberately struck this particular nuclear infrastructure facility.

“As of now, there are no readings exceeding normal background radiation levels. But there is certainly an increase in Russia’s brazenness, which long ago went off the charts. Ukrainian first responders extinguished the fire at this facility after the strike.

“And real new steps by the world are needed so that the Russians feel that this terrorist war of theirs is a blow to Russia itself.

“Last night, there were also Russian strikes on other civilian facilities in 13 of our regions. In total, over the course of this past week, Russia launched 88 missiles, more than 3,250 attack drones, and around 1,800 guided aerial bombs against Ukraine.

“Pressure on Russia must be increased. Thank you to everyone who’s helping!”

General Sir Richard Shirreff, who chairs an advisory council for Ukraine's armed forces, has hit out at the PM, accusing him of having "failed to put together" a long-promised defence investment plan.

An influential group of MPs has said the government should apologise for the delay, which has damaged Britain’s safety.

The UK has pledged support for Ukraine in its fight against Russia.

Sir Richard told BBC Radio 4's Broadcasting House "it's going to be very difficult for the prime minister to look President Zelensky in the eye and indeed his other allies, particularly Germany" when he has "failed to put together" the promised defence investment plan.

The PM, alongside the leaders of France and Germany, will hold talks with the Ukrainian President on how to increase pressure on Moscow later.

It comes after Russia suffered a series of military setbacks.

Ukraine has recaptured more territory than it lost to Russian forces in May for two straight months, an analysis by the AFP news agency shows.

Today’s meeting will allow the leaders to “continue their ​close coordination on our shared agenda of ​continuing support for Ukraine and increasing pressure on ⁠Russia’s war effort", France has said.

Earlier this week President Zelenskyy proposed a face-to-face meeting with Vladimir Putin in an open letter.

But the Russian leader has rejected the idea. Could another push bring him to the negotiating table?

Russia's Defence ⁠Ministry said on ⁠Sunday its ​air ⁠defences ⁠had ​downed ⁠500 ‌Ukrainian drones ‌in the ‌past ⁠24 hours, Interfax news agency reported.

Armenian authorities have arrested six candidates from a pro-Russian opposition party, state media reported, just a day before they were due to stand in general elections. No official reason was given for the Saturday detentions.

The candidates belong to the Strong Armenia party, led by Russian-Armenian billionaire Samvel Karapetyan. Mr Karapetyan is currently under house arrest himself, facing charges of calling for the overthrow of the government – accusations he dismisses as politically motivated.

These arrests occur as Armenia's relationship with its traditional patron, Russia, has become a central electoral issue. Moscow recently imposed restrictions on Armenian exports, widely interpreted as a response to Yerevan's warming ties with Western countries.

In Ukraine, one person was killed and three wounded overnight into Saturday in the Dnipropetrovsk region, as Russian forces struck three districts nearly 30 times with drones and artillery, regional head Oleksandr Hanzha said.

Vladimir Putin on Friday rejected a proposal by Mr Zelensky for face-to-face talks on the four-year-old war, claiming he saw “no point” in a meeting.

The so-called E3 group of nations meeting the Ukrainian leader are some of Kyiv’s staunchest allies, with the UK and France leading the “coalition of the willing” initiative to provide security guarantees for Ukraine as part of a peace process.

Armenians are going to the polls today in a key parliamentary election, faced with a choice between an incumbent government seeking to deepen its ties with the West and several opposition parties that are vocally pro-Russian.

Prime minister Nikol Pashinyan and his ruling Civil Contract party have advocated for a balanced foreign policy ensuring Armenia maintains good relations with the United States, Europe and Russia, as well as regional powers such as Turkey and Iran.

Trump has endorsed Pashinyan, while Russian officials have hit Armenian exports with a barrage of restrictions in recent weeks, and high-ranking officials, including Vladimir Putin, have made thinly veiled threats comparing Armenia’s path to that already taken by Ukraine.

Putin also has stressed that Armenia cannot join the EU and remain within the Eurasian Economic Union, a Russian-led customs bloc.

“Being in a customs union with the European Union and the Eurasian Economic Union is impossible,” Putin said. “It’s simply impossible by definition.”

Other potential contenders include former President Robert Kocharyan, who leads the Hayastan bloc and has accused Pashinyan of “seriously undermining” relations with Russia, and the Prosperous Armenia Party led by pro-Russian business owner Gagik Tsarukyan.

Polls opened at 8am local time this morning, with first results expected this evening or early Monday morning.
