Assad's government denies using chemical weapons, and Russian Federation has offered competing explanations for the chaotic scenes of April 7, first denying that an attack took place, then saying it had been staged by rebels.
Spokeswoman Heather Nauert said the team of inspectors from the Organisation for the Prohibition of Chemical Weapons (OPCW) had not been given access to the site of the alleged attack in the town of Douma on April 7.
"According to the information we have, the special OPCW mission... arrived on the morning of April 21 in the city of Douma at the sites suspected of having toxic substances", the ministry said in a statement.

The attack in Douma, the eastern Damascus town now fully under Syrian government control after a years-long siege, is believed to have killed dozens. Russian Federation and its ally deny that.
Stephane Dujarric told reporters at U.N. headquarters Thursday that "due to the volatility" of the situation on the ground in Douma the United Nations doesn't want "to telegraph" when a U.N. security team will return to Douma to check out whether conditions on the ground are safe for the inspectors to visit.
He added that while the United States could not know with certainty, there was no evidence that any chemicals had escaped into the air after the strike.
"Speaking about risks of a military confrontation, I am 100 percent sure that [both the US and Russian] militaries won't allow this, and of course neither will President [Vladimir] Putin or President [Donald] Trump", he said.More news: Canadian musicians celebrate Record Store Day
Lavrov was also quoted as saying that, prior to the US strikes on Syrian targets, Russian Federation had told USA officials which areas of Syria represented "red lines" for Moscow, and the USA military action did not cross those lines. The U.S., Britain and other Western allies responded by expelling over 150 Russian diplomats, and Moscow, which has fervently denied the British accusations, responded in kind.
Syria's resurgent president, whose job hung by a thread earlier in the conflict, appeared determined to press on with his Russian-backed military recovery. It is probably spread throughout the country at a variety of sites", said Lieutenant General Kenneth McKenzie, joint staff director."They will have the ability to conduct limited attacks in the future, I would not rule that out.
"However", he added, "as they contemplate the dynamics of conducting those attacks, they've got to look over their shoulder and be anxious that we're looking at them and we'll have the ability to strike them again should it be necessary".

The United States, the UK and France said the strikes had been a response to the alleged chemical attack in Syria's Douma. Chlorine is a gas at room temperature and therefore unlikely to remain at the scene, experts say, while traces of nerve agent are likely to fade fast. "We sought to send a lesson that it's bad practice to gas women and children", McKenzie said.
