LONDON, Oct 13 (Reuters) - The Kremlin was quoted as saying on Thursday that the goals of its "special military operation" in Ukraine are unchanged, but that they may be achieved through negotiations.The comments by Kremlin spokesman Dmitry Peskov to Russian newspaper Izvestia were the latest in a series of statements this week stressing Moscow is open to talks - a change of tone that follows a series of humiliating defeats for Russian forces as the war in Ukraine nears the end of its eighth month."The direction has not changed, the special military operation continues, it continues in order for us to achieve our goals," Peskov was quoted as saying.Foreign Minister Sergei Lavrov said on Tuesday that Moscow was open to talks with the West, but the United States dismissed the statement as "posturing".Ukrainian President Volodymyr Zelenskiy has ruled out talking to President Vladimir Putin after Russia proclaimed the annexation of four Ukrainian regions last month and rained missiles on Ukrainian cities this week in the wake of an attack on a vital bridge between Russia and annexed Crimea."
