Putin describes Ukraine as the "heir to Nazism" Ukrainians strike Belgorod after a night of raids against Kiev, Odessa and other regions. Russia canceled this year for security reasons the march of the Immortal Regiment, which is traditionally held on Red Square on May 9 after the military parade for the anniversary of the victory over the Nazis.

"When dealing with a state that actually sponsors terrorism, it is better to take precautions," Kremlin spokesman Dmitry Peskov said, referring to Ukraine.
