Government backed forces want to retake Idlib and adjacent areas of northwestern Syria.
"To recapture eastern Ghouta in April, government forces launched numerous indiscriminate attacks in densely populated civilian areas, which included the use of chemical weapons", it said, referring to incidents on January 22 and February 1 in a residential area of Douma, eastern Ghouta, outside the capital. Should an attack take place, Pentagon planners have drawn up a list of possible USA military responses. On Monday, Bolton called that statement "one of the most outrageous claims that I can think of" in the history of propaganda.
Last week, the United Nations warned that such an offensive would likely lead to the "worst humanitarian catastrophe of the 21st century".
"Innocent people must not be sacrificed in the name of fighting terrorism", he wrote.
On Monday, a top United Nations humanitarian official, Mark Lowcock, said that unless some way of "dealing with this problem" was found, what is about to transpire in Idlib could descend into "the worst humanitarian catastrophe, with the biggest loss of life of the 21st century".
Although no decision has been made to strike Assad's forces, he noted that the president "expects us to have military options, and we have provided updates to him on the development of those military options".
However, the jihadists are expected to continue waging insurgent attacks in both Iraq and Syria. Russian Federation was the framework guarantor of removing all the chemical weapons, but apparently did not live up to the deal.More news: Larger iPhones revealed: Dual SIM XS, XS Max in new gold, 512GB

White House Press Secretary Sarah Huckabee Sanders warned last week that the USA will respond "swiftly and appropriately" should Assad use chemical weapons against the Syrian people, and Pentagon spokesman Col. Rob Manning explained Monday that "the use of chemical weapons will not be tolerated by the US or the coalition".
When asked what the US has done to prevent their use, Mattis referred to US, UK and French strikes on Syria after a chemical weapons attack in April.
Afrin's main hospital, a market and homes were hit, it said. The third target was the Barzah Research Center, a military facility located near Damascus that conducted research, development, production and testing of chemical and biological warfare technology. The Pentagon has already begun preparing military options should the president decide to respond militarily to any use of chemical weapons in the Idlib offensive. The US and other Western powers claimed that Syria attacked Douma with sarin, a lethal nerve agent, and followed that with a chlorine attack, intended partly to hide the sarin. The Administration has been deliberately vague on the topic.
A possible regime attack on Syria's northwestern province of Idlib will sabotage the ongoing political process and cause a serious crisis of confidence, the Turkish presidential spokesman said on September 11. The Russians and Iranians would be making a grave humanitarian mistake to take part in this potential human tragedy. "Don't let that happen!"

Last week, Russian and Syrian warplanes resumed a bombing campaign in Idlib, the last rebel enclave in Syria, after weeks of quiet, in an apparent prelude to a full-scale offensive.
Syrian ground forces, however, remain on the outskirts of the province, awaiting orders to invade.
