He criticized Washington and its allies for attacking without waiting for inspectors from the worldwide chemical weapons watchdog group to visit Douma, just outside Damascus. New National Security Adviser John Bolton - who started Monday - and Vice President Mike Pence were also on hand.
Russian Federation in November used its veto three times to bury a previous UN-led inquiry which found that Syrian forces had used sarin in the attack on Khan Sheikhun in April past year.
Inspectors from the independent Organisation for the Prohibition of Chemical Weapons (OPCW) are now in Damascus. It has met with Syrian officials but has not visited the town at the centre of the controversy. Bush addressed sailors aboard a ship in May 2003 alongside a "Mission Accomplished" banner, just weeks before it became apparent that Iraqis had organized an insurgency that tied down US forces for years.
Just few days back, US President Donald Trump had announced that the US would like to exit from the Syrian theatre but, it appears that now, it would be hard for them to withdraw at least in near future.
The following Iraqi insurgency, which dragged on for years, led to widespread ridicule of the term. Syria denies responsibility and says it gave up its chemical arsenal.
What is happening in Douma?
The air wing in Assad's army that the United States suspects of having carried out a chemical attack earlier this month on the town of Douma went unpunished.
"It shows that the USA and its allies won't start a full-scale war with Russian Federation, and they are not trying to destroy the Syrian government", said Gu Zhenglong, a senior research fellow at the Xinhua Center for World Affairs Studies. They didn't change who's winning the war, did they - these strikes?
But Assad has been publicly spanked by the USA, the United Kingdom, and France.
The Western trio swiftly reverted to diplomatic efforts, with leaders facing flak at home over the punitive attack. The Western countries blame Assad for the Douma attack that killed dozens of people.
Media captionSyria air strikes: Do they work?
Donald Trump declared "mission accomplished" on Twitter following strikes on Syria's chemical weapons plants, but the attack has failed to dampen Bashar al-Assad's ardour for slaughtering his people.
Britain's Foreign Secretary Boris Johnson leaves 10 Downing Street in London on March 27, 2018.
"According to the cowardly statements and the weak strike by the West, Assad is allowed to use all kinds of weapons to kill us except chemicals", tweeted Syrian opposition journalist Hadi Abdallah. But let's be clear: Friday night's strikes were "just muscular enough not to get mocked". "This is not about trying to turn the tide of the conflict in Syria", he told the BBC, adding that Russian Federation was the only country able to pressure Assad to negotiate an end to the conflict.
She called for a full parliamentary debate on the matter.
But Russia has blocked countless resolutions against its Syrian ally and the regime has appeared determined to continue its military reconquest of the country.
The vote followed bitter exchanges, with Russian Federation accusing the allies of "cynical disdain" and the USA saying that Russian Federation had trashed diplomatic moves on chemical weapons. According to a Pentagon official, targets were selected that participated in the research, development and deployment of chemical weapons.
Russian President Vladimir Putin warned Sunday western powers that further attacks in Syria will bring "chaos" in worldwide relations.
What was targeted by the US, UK and France?
The site west of the city of Homs was an alleged underground chemical weapons storage facility, doubling as a command post. We hit the sites, the heart of the chemical weapons programme.
"We assess this was the primary location of Syrian sarin and precursor production equipment", Dunford said.
Pentagon chief Jim Mattis says there are no reports of us losses in what he describes as a heavy but carefully limited assault. Three nations told Syria, and its Russian backers, they meant business after years of turning a blind eye to reports of horrors in the country.
