US President Joe Biden said Thursday that Russian leader Vladimir Putin's order for a two-day Orthodox Christmas ceasefire in Ukraine was simply an effort to find breathing room for his war effort.State Department spokesman Ned Price called Putin's ceasefire "cynical," saying, "We have little faith in the intentions behind this announcement."He voiced concern that Russia would use the break to "regroup, to rest and ultimately to re-attack" and said that Putin may seek to "fool the world" by making it seem that he wants peace."If Russia were truly serious about peace, about ending this war, it would withdraw its forces from the sovereign territory of Ukraine."Wagner boss Yevgeny Prigozhin appeared in a video speaking to a gathering of men -- some injured and whose faces were blurred."
