MOSCOW, March 23. /TASS/. The reaction of the US authorities to the terrorist attack at the Crocus City Hall raises big questions, in particular, as to the reasons why the White House takes the liberty of claiming right away Ukraine was not involved in the incident, Russian Foreign Ministry spokeswoman Maria Zakharova has said.

"There are also reactions [to what happened at Crocus City Hall] that raise more questions. This certainly concerns comments from Washington, which said it saw no signs that Ukrainians might be involved in the terrorist attack," Zakharova said on the Rossiya-24 television channel.

"What grounds Washington officials are using to draw any conclusions in the midst of the tragedy about someone’s noninvolvement is a big question," Zakharova added. "If the US or any other countries had reliable information on that it should have been provided to the Russian side immediately. If there is no such information neither the White House nor anyone else has the right to indulge anyone," she noted.

"To be honest, the reaction of the UN Secretary-General’s secretariat raises not simply questions, but big questions, as he stated, I mean the secretariat of his representative, that they are saddened by reports of shooting," the spokeswoman said, adding that all adequate people, even considering various emotional level, had similar reaction: terror, shock, bewilderment, unconditional condemnation and compassion.

"What does sadness about shooting mean? Maybe no one else, but the United Nations and the secretariat of the UN in particular, and Secretary-General of this structure, and [UN] member-states should see what the rest of the world sees now, a bloody terrorist attack, and unconditionally condemn it," she stressed.
