Putin's call for Orthodox Christmas truce in Ukraine greeted with scepticism- Summary- Companies- Putin orders ceasefire to start at noon on Friday- Ukraine says no truce until invaders leave- Germany, U.S. agree to send combat vehicles to UkraineKYIV/BAKHMUT, Ukraine, Jan 5 (Reuters) - Russian President Vladimir Putin called on Thursday for a 36-hour ceasefire in Ukraine to mark Orthodox Christmas, a move rejected by Kyiv which said there could be no truce until Russia withdraws its troops from occupied land.The United States and Germany made a joint announcement to supply Ukraine with armoured combat vehicles, a boost for Ukrainian President Volodymyr Zelenskiy who has urged Western allies to provide his forces with armour and heavy weapons for months."Proceeding from the fact that a large number of citizens professing Orthodoxy live in the areas of hostilities, we call on the Ukrainian side to declare a ceasefire and allow them to attend services on Christmas Eve, as well as on Christmas Day," Putin said in his order."They now want to use Christmas as a cover, albeit briefly, to stop the advances of our boys in Donbas and bring equipment, ammunitions and mobilised troops closer to our positions," Zelenskiy said in his nightly video address, speaking pointedly in Russian rather than Ukrainian.Earlier on Thursday, the Kremlin said Putin had told Turkey's President Tayyip Erdogan that Moscow was ready for peace talks - but only under the condition that Ukraine "take into account the new territorial realities", a reference to Kyiv acknowledging Moscow's annexation of Ukrainian territory."
