REPORTS OF EXPLOSIONS AT AN OIL DEPOT IN CRIMEA

In Russian-occupied Crimea, loud explosions were heard near an oil depot in the early hours Sunday, according to a local pro-Kyiv Telegram news channel. Kremlin-installed officials in the territory said a nearby stretch of highway was closed for about eight hours.

Videos shared with pro-Ukrainian channel Crimean Wind showed explosions lighting up the sky, followed by booms. The channel said they were taken by residents near Feodosia, a coastal town in northeastern Crimea. It was not immediately possible to verify the circumstances in which the videos were shot.

An anti-Russian, Crimean Tatar-led underground group claimed that the blasts destroyed a pipeline, causing 鈥渃olossal鈥 damage.

The group, Atesh 鈥 which means 鈥渇ire鈥 in Crimean Tatar 鈥 did not directly claim responsibility for the strike and said it had learned about its consequences from informers among Russian-appointed officials. Authorities in Kyiv did not immediately acknowledge the claims.

Traffic was halted early Sunday along a four-lane Russian federal highway near Feodosia, according to an adviser to Crimea's Kremlin-installed leader. The Telegram post by Oleg Kryuchkov gave no reasons for the move.

More than eight hours later, Crimea's local transport minister reported that traffic had partially resumed. A bridge that connects Crimea to Russian territory was also closed to traffic for about two hours early Sunday

Russia鈥檚 defense ministry did not comment on the reports but claimed that 38 Ukrainian drones were intercepted overnight into Sunday over the peninsula.

CHINA'S UKRAINE ENVOY HOLDS TALKS IN MOSCOW

In Moscow, China鈥檚 special envoy on Ukraine held talks on Saturday evening with senior Russian diplomats in the first leg of a European trip that will also take him to Brussels, Poland, Germany and France, Chinese and Russian state media reported.

China鈥檚 foreign ministry said Special Representative Li Hui and Russian Deputy Foreign Minister Mikhail Galuzin agreed that negotiations are the only way to end the fighting in Ukraine.

Li鈥檚 trip, the second since May, comes as Kyiv seeks Beijing鈥檚 participation in peace talks that Switzerland is trying to organize. China claims it is neutral in Russia鈥檚 war on Ukraine but maintains close ties with Moscow, with frequent state visits and joint military drills.

On Sunday, Turkish Foreign Minister Hakan Fidan said it was time to start discussing a cease-fire between Moscow and Kyiv, claiming that 鈥渂oth sides have now reached the limits of the results they can achieve through war.鈥

Speaking at a news conference, Fidan said that such a move would not mean recognizing Russia's occupation of parts of Ukraine.

鈥淲e believe that it is time to separate the issues of recognition of the occupation and sovereignty from the cease-fire issue,鈥 he said.
