KYIV, Ukraine — Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks, the Ukrainian air force said Monday, after the Kremlin effectively rejected an unconditional 30-day ceasefire in the more than three-year war, but reiterated that it would take part in possible peace talks later this week without preconditions.
There was no direct response from the Kremlin, meanwhile, to Ukrainian President Volodymyr Zelenskyy's challenge for Russian leader Vladimir Putin to meet him for face-to-face peace talks in Turkey on Thursday.
Kremlin spokesman Dmitry Peskov on Monday refused to say who might travel to Istanbul from the Russian side.
''Overall, we're determined to seriously look for ways to achieve a long-term peaceful settlement. That is all,'' Peskov said.
The United States and European governments are making a concerted push to stop the fighting, which has killed tens of thousands of soldiers on both sides, as well as more than 10,000 Ukrainian civilians. Russia's invading forces have taken around one-fifth of Ukraine in Europe's biggest conflict since World War II.
In a flurry of diplomatic developments over the weekend, Russia shunned the ceasefire proposal tabled by the U.S. and European leaders, but offered direct talks with Ukraine on Thursday.
Ukraine, along with European allies, had demanded that Russia accept a ceasefire starting Monday before holding peace talks. Moscow effectively rejected that proposal and instead called for direct negotiations in Istanbul.
