Russian troop build-up threatens city seen as key to seizing Ukraine's Donbas Russian troops have infiltrated the strategic city of Kostyantynivka in eastern Ukraine and are now trying to surround it. The entire city is now effectively in a grey zone, no longer controlled by anyone, Ukrainian soldiers have told the BBC. They get into areas behind our backs and in urban conditions it's extremely difficult to push them out, says a Ukrainian drone pilot who operates in that area and prefers to remain anonymous. Kostyantynivka is a gateway to the rest of the Donbas region. If it falls, Russian forces would be able push towards Ukraine's last remaining strongholds in the east, the cities of Kramatorsk and Sloviansk, and move closer to seizing Donbas completely, one of the Kremlin's key objectives in this war.

Is the war entering a new phase? Russia has renewed its strikes on Ukraine, killing three people including an eight-year-old girl, Ukrainian officials said. The Russian strikes on Friday come a day after Ukraine launched its biggest-ever drone attack on Moscow, killing a different eight-year-old girl and sparking an inferno at a major oil refinery, according to Russian officials. Between late Thursday and early Friday, Russia launched 90 drones at Ukraine, according to the Ukrainian air force. "An eight-year-old girl was killed. These are the consequences of this morning's enemy attack on Pavlohrad," Oleksandr Ganzha, the governor of Ukraine's central Dnipropetrovsk region, said.

Ukraine launched one of its largest drone attacks on Moscow, striking a major oil refinery and sending thick black smoke over the capital, according to Russian officials.

Moscow hit by largest Ukrainian attack since start of Russia's full-scale war Moscow has come under the largest Ukrainian attack since the start of the full-scale war, with close to 200 drones hitting targets around the Russian capital and setting columns of thick smoke billowing high into the sky. Seventeen people were wounded in the Moscow region, according to local governor Andrei Vorobyov. Almost 1,000 drones and four Ukrainian cruise missiles were intercepted and destroyed across the country in 24 hours, Russia's defence ministry was quoted as saying. An oil depot was struck in the southern Rostov region, where one person was killed. Volodymyr Zelensky said Kyiv had once again hit the Moscow region with long-range sanctions - a euphemism for Ukrainian long-distance strikes on Russia.

Russia’s defense ministry said 555 drones were shot down across the country. Sobyanin said 180 were shot down around Moscow alone.

The boss of Cadbury chocolate-maker Mondelez has defended its decision to continue doing business in Russia but admitted he is not pleased the firm's taxes are funding the war with Ukraine. Chief executive Dirk Van de Put said it was the right decision to stay after Russia invaded Ukraine in 2022, saying pulling out would risk thousands of jobs and leave Mondelez vulnerable to the Kremlin taking control of its local operations. Many Western companies such as McDonald's exited Russia after it launched a full-scale assault on its neighbour. Others remained but Mondelez said it had discontinued new investment in its Russian business and suspended spending on advertising. In an in-depth discussion as part of the BBC's Big Boss Interview series, Van de Put said: I think over time you try to be neutral in the whole conflict.

Ukrainian forces have carried out a missile attack deep inside Russia, hitting a major military plant overnight, President Volodymyr Zelensky has said. He said FP-5 Flamingo cruise missiles struck the drone and missile plant in the city of Cheboksary, in the Chuvash Republic, more than 900km (560 miles) from the front line. Local officials said three people were injured in a missile attack on the city. Ukraine also said it had hit the Moscow-occupied port of Mariupol on the Sea of Azov, a Russian oil refinery in Samara and a shadow fleet oil tanker in the Black Sea. In recent months, Ukraine's military has intensified its drone strikes on key facilities across Russia.

'No-one feels safe now': Residents of Romanian city hit by drone share fears In some parts of Europe, Russia's full-scale invasion of Ukraine can feel like a distant threat. But in Romania, that war is right next door and increasingly dangerous. In Galati, there is an apartment block with a hole in the roof that proves it. Residents have just begun returning to check on their homes, after an attack drone slammed into the building early on Friday as dozens of people slept. It sparked a fire and panic.

Belgium and France have summoned Russia's ambassadors to express anger after Moscow urged foreigners to leave Kyiv in advance of planned "systematic strikes". Brussels and Paris said on Wednesday that Russia's announcement earlier in the week was "unacceptable" and a violation of international law. The spat is unlikely to help smooth the way for the EU to mediate talks to bring the conflict to an end, an arrangement that Russian President Vladimir Putin said on Wednesday he is ready to accept. Germany, the Netherlands, Norway and the European Union summoned Russian envoys on Tuesday following Moscow's warning that foreigners and diplomats should leave the Ukrainian capital before the onset of renewed air strikes . "Threatening embassies is not diplomacy, it is intimidation. And it is a flagrant violation of international law and the Vienna Convention," Belgium Foreign Minister Maxim Prevot said on Wednesday.

'Leave Kyiv': Why Russia's latest Ukraine threat is a major escalation Russia has urged foreigners to leave in Ukraine's capital Kyiv, and warned of more strikes on the city, suggesting a major escalation in its more-than-four-year-long war on Ukraine. In a statement issued on Monday, Russia's Ministry of Foreign Affairs said it planned to target "decision-making centres and command posts" and drone manufacturing facilities in the Ukrainian city in a series of strikes. The ministry's statement also urged Kyiv residents to avoid all military and administrative infrastructure facilities in the capital, which could be potential targets. A later statement said that Russian Foreign Minister Sergey Lavrov had advised US Secretary of State Marco Rubio of the plan and urged him to evacuate his embassy staff from Kyiv. Moscow said these planned strikes were in response to a drone strike on a student dormitory in Starobilsk, in the Russian-occupied Luhansk region of Ukraine, which killed at least 18 people. The threats come just days after Russian drone and rocket strikes on Kyiv on Saturday night killed at least four people and injured about 100 others.
