Russian President Vladimir Putin is stalling over a ceasefire. Meanwhile, Trump has changed his mind about sending weapons to Ukraine.

Russia and Ukraine appear close to agreeing to hold a new round of peace talks in Turkey this week, although the Kremlin said on Monday that the two sides held "diametrically opposed" positions on how to end the war.

Russia and Ukraine will hold a new round of peace talks in Istanbul on Wednesday, Ukrainian President Volodymyr Zelensky has said.

The barrage of exploding drones and missiles appeared to be the most intense attack since President Trump announced a plan to get more weapons for Kyiv.

A Russian factory, described by its director as the world's biggest maker of strike drones, has been shown on the Russian army's TV channel with teenagers helping make kamikaze drones to attack Ukraine.

Russian aviation faced big delays due to the threat posed by Ukrainian drones, while Moscow's attacks on Ukraine killed at least one person.

Russia is open to peace with Ukraine, but achieving its goals remains a priority, Kremlin spokesman Dmitry Peskov said Sunday, days after U.S. President Donald Trump gave Moscow a 50-day deadline to agree to a ceasefire or face tougher sanctions.

Both Russia and Ukraine are sending more fiber-optic drones to the battlefield, but despite their advantages, they still have their limitations.
