Ukraine says Russia launched an intercontinental ballistic missile, one carrying a conventional warhead, toward it. ICBMs can also be used to launch nuclear weapons, and Russian President Vladimir Putin recently lowered the bar for using nuclear weapons in what appeared to be a threat to the U.S. and its NATO allies.

The Rostov region in Russia may be the next target of Ukrainian missile attacks, reports "The Wall Street Journal". This region is a key strategic point for Russian forces. Russian airports and ammunition depots are at risk following Ukraine's receipt of permission to attack targets within Russia.
