Russia planned to start the invasion with a "massive missile and airstrike campaign" against Ukrainian military targets, RUSI says, with a list also showing who should be killed, who would be intimidated and who would be targeted as a collaborator. A British defence and security think tank has revealed details of Moscow's pre-invasion plan for Ukraine, based on captured Russian documents apparently signed off by Vladimir Putin. Russia had planned to take over Ukraine over 10 days and annex it by August this year, the Royal United Services Institute for Defence and Security Studies (RUSI) said.
