Ukraine Today is reporting that T-90A tanks have been identified operating near Luhansk in east Ukraine. If true, this would be evidence of Russian involvement in the fighting in Donbas.

This (if true) is blatant. Is an outright admission of Russian forces in Ukraine and will require a response. Just wow.
