these last three nights have represented the most serious, most intense attacks since the war began last year. >> please stay safe and thank you. also, there is possible proof of life of yevgeny prigozhin. the wagner leader sent a grainy telegram leader that appears to show him alive and well greeting soldiers in belarus. cnn has not independently confirmed this is prigozhin but if so, it would be the first time he's been seen in public since he led the attempted mutiny nearly a month ago. the whole saga has western officials scratching their heads over how it happened and how he's still alive. even britain's spy chief, richard moore, the head of mi 6, i should note, rarely speaks out in public and certainly not as candidly today and said he was stumped. >> prigozhin started off as a traitor at breakfast.
