Pure BS. Ukraine has never targeted civilian targets, unlike Russia. They only go after infrastructure tied to the war machine. Oil refineries and rail. The US even told them these assholes were planning this last month, and they handwaved it away.

If you'd be ISIS, you'd probably blow yourself up in your workshop, since judging from your comments, you don't understand reality as much as you think you do. Which ironically is kind of a requirement for joining a religious terrorist group.
