The White House has reportedly accused the Russian government of engaging in a cover-up of the Syria chemical weapons attack on Tuesday, April 11, 2017.

According to a report by New York Times, the White House explained that United States intelligence and numerous contemporaneous reports confirmed that the Syrians used sarin gas on their own people.

The report further said the White House asserted that the Syrian and Russian governments have sought to confuse the world community about the assault through disinformation and “false narratives.”

White House sources reportedly said Russia’s goal was to cover up Syrian regime culpability.

The sources reportedly said they could not comment on the possibility that the Russian government knew in advance of Syria’s plan to carry out the chemical weapons attack, or of a subsequent attack on a hospital that was treating victims.

Another source said Moscow must answer for the attacks due to the history of close cooperation between the Syrian and Russian militaries.

The report also hinted that Pentagon officials have said that Russian personnel were at the Syrian base used to launch the chemical weapons attack.
