Moscow says US has no objective data on monstrous crime in Syria

Moscow: The Kremlin on Thursday said US allegations that Syrian forces carried out a deadly chemical attack are not based on "objective" information.

"We consider a much more measured approach necessary and do not think it is possible to surrender oneself to hasty conclusions about what happened in Syria in the Idlib province," Kremlin spokesman Dmitry Peskov told reporters. 

"It was really a threatening development of events, very dangerous and a monstrous crime," he said, referring to the incident.

"No one could have any realistic, verified information. Any data that the American side or our colleagues in other countries could have cannot be based on objective materials or evidence." 

The White House has accused the forces of Syrian President Bashar al-Assad of carrying out a suspected chemical attack in rebel-held Khan Sheikhun that killed scores.

Russia has sought to deflect blame from its ally Assad and said that Syrian jets hit a rebel arms depot holding "toxic substances" that were being placed in bombs.
