A Ukraine army boss claimed Russian President Vladimir Putin has cancer and is in a 'very bad condition'.
Major General Kyrylo Budanov said: "Mr Putin is in a 'very bad psychological and physical condition and he is very sick'.
He claimed the Russian President has cancer and 'illnesses', while dismissing suggestions he was spreading propaganda.
"It's my job, it's my work, if not me who will know this," he added.
Ukraine's head of military intelligence predicted the war with Russia would end a turning point by the middle of August and would be over by the end of the year.

He said he was 'optimistic'.
General Budanov said they would gain back Ukrainian power in all the territories they have lost including the Donbas and Crimea.
He also told Sky News defeat in Ukraine would lead to the removal of Russia's leader.
It comes after Budanov said Ukraine will fight for the remote Zmiinyi Island (Snake Island) in the Black Sea "for as long as is needed".
