By Vladimir Soldatkin, Tom Balmforth and Huseyin HayatseverISTANBUL (Reuters) -Russia told Ukraine at peace talks on Monday that it would only agree to end the war if Kyiv gives up big new chunks of territory and accepts limits on the size of its army,

Russian and Ukrainian delegates met in Istanbul on Monday for their second set of direct peace talks, a day after Kyiv launched a shock drone attack on Russia’s nuclear-capable bombers, in an operation that President Volodymyr Zelensky said was a year and a half in the making.

A Ukrainian drone attack has destroyed more than 40 Russian planes deep in Russia’s territory, Ukraine’s Security Service said on Sunday, while Moscow pounded Ukraine with missiles and drones just hours before a new round of direct peace talks in Istanbul.
