The United States on Monday slammed Russia and China for their failure to condemn an attack last week on its Baghdad embassy by pro-Iranian demonstrators.

While congratulating the 27 of the 193 member nations that did issue statements condemning the December 31 attempt to storm the compound, the US mission to the UN said that Russian and Chinese silence undermined the Security Council.

“Not allowing the United Nations Security Council to issue the most basic of statements underscoring the inviolability of diplomatic and consular premises once again calls the council’s credibility into question,” the US statement said.
