"West protests too much about Kiev’s possible role in Moscow terror attack – Lavrov" https://www.rt.com/russia/595090-west-suspiciously-denying-ukraine-crocus/

The intensity of their insistence on Ukraine’s innocence is unusual, the Russian foreign minister has said

“The West is actively trying to convince everyone that this is the work of ISIS and there is no longer any need to suspect anyone, especially Ukraine,” Lavrov told Izvestiya in a video interview published on Friday. “They keep insisting that Kiev is not to blame, to the point where it’s becoming obsessive.”

“We have repeatedly said that we do not make any final conclusions until the investigation is completed. The investigation is still working on the facts, new circumstances are being revealed, but we simply do not have the right to exclude obvious possibilities,” the foreign minister said.

Meanwhile, Lavrov said, the West is “suspiciously active” in trying to persuade everyone that Ukraine had nothing to do with the attack.
