Russian President President Vladimir Putin announces military operation in eastern Ukraine’s Donbas region. In response the US President Joe Biden denounced “unprovoked and unjustified” attack on Ukraine, pledging the world will “hold Russia accountable”. Since the attack the UN Security Council members are holding an emergency meeting amid mounting tensions. The Kremlin says Ukraine separatists have asked Moscow for “help” against Kyiv which is why they needed to send in troops. The story is fluid and is changing by the moment.
