The group says the mission "will continue its deployment to the Syrian Arab Republic to establish facts around the allegations of chemical weapons use in Douma."

Mayhoub says the attacks "will not deter" the Syrian military from its ongoing war to eradicate "armed terrorists" from Syrian territory.
6:48pm: France's foreign minister says the "chemical escalation" in Syria is not acceptable because it's violating the rules of war and of humanity.

She added that "with our allies, we ensured that the Russians were warned ahead of time.

In Damascus, the president's seat of power, hundreds of residents gathered in Omayyad Square, many waving Syrian, Russian and Iranian flags.

The network says the building in the research center included an educational center and labs.
4.17pm: NZ Prime Minister Jacinda Ardern has releases a statement on the US, UK and French strikes on Syria. She says the government "accepts" the strike but always favours "diplomatic efforts".
“The Government has always favoured diplomatic efforts and a multilateral approach. The use of the veto powers at the Security Council prevented that course of action. We have always condemned the use of the veto, including by Russia in this case," she wrote.
"New Zealand therefore accepts why the US, UK and France have today responded to the grave violation of international law, and the abhorrent use of chemical weapons against civilians.
"The action was intended to prevent further such atrocities being committed against Syrian civilians.
"We stand firm in our condemnation of the use of chemical weapons in Eastern Ghouta. This is clearly in breach of international law.
"It is now important that these issues are returned to the United Nations multilateral processes including the Security Council."
3.55pm: Russian Foreign Ministry spokeswoman Maria Zakharova has issued a statement on Facebook. She wrote the US strikes on Syria come as the country was entering a chance for peace, and have been instigated off inaccurate media reports on the Assad chemical attack in Douma.
"One must be really exceptional to strike Syria’s capital when the country finally got a chance for a peaceful future," Zakharova wrote.
"The White House said that the confidence in the Damascus standing behind the chemical attack is based on 'the media, reports of symptoms, videos and photos, as well as on credible information'.
"15 years ago, the White House used a test tube and its State Department, now instead of a test tube Washington has used the media."
3.45pm: Syrian State TV is reporting "we have news of shooting down 13 missiles belonging to the US-British-French aggression in the area of Kiswah in the suburbs of Damascus".

Senate Armed Service Committee Chairman John McCain is applauding the airstrikes but says "they alone will not achieve US objectives in the Middle East".
And House Minority Leader Nancy Pelosi says, "One night of airstrikes is not a substitute for a clear, comprehensive Syria strategy".

3.05pm: US Defense Secretary James Mattis says today's strikes have "sent a clear message" to Assad and his "murderous lieutenants."

He is asking that "responsible nations" join in condemning the Assad regime.
2.53pm: A highly placed Russian politician is likening President Donald Trump to Adolf Hitler after the launch of airstrikes against Syria, and says he regards the action as a move against Russia.
Alexander Sherin, deputy head of the State Duma's defense committee, says Trump "can be called Adolf Hitler No. 2 of our time - because, you see, he even chose the time that Hitler attacked the Soviet Union."
That's according to state news agency RIA-Novosti.
2:44pm: All eyes will now be on Russia's response to the strike. Defence Secretary Mattis says Russia had no foreknowledge of the airstrikes in Syria.
2:40pm: A dramatic image captures missiles streaking over Damascus in Syria.
2:32pm: An ominous tweet.
2:29pm: The British Defence Ministry says "initial indications" show that the airstrikes against Syria produced a "successful attack" on a Syrian military facility.
British Prime Minister Theresa May is describing the attack as neither "about intervening in a civil war" nor "about regime change," but a limited and targeted strike that "does not further escalate tensions in the region" and does everything possible to prevent civilian casualties.
May says, "We would have preferred an alternative path. But on this occasion there is none."
2:26pm: Mixed messages from the White House and the Pentagon, with President Donald Trump saying this will be a "sustained" attack and Defence Secretary James Mattis saying these are only targeted strikes aimed at taking out chemical weapons.
2:20pm: Defence Secretary James Mattis says the US has no reports of suffering any losses during the initial airstrikes on Syria today.
The story so far:
Loud explosions lit up the skies over the Syrian capital, as Trump announced the airstrikes.
In an announcement from the White House, Trump said the US is prepared to "sustain" pressure on Assad until he ends what the president called a criminal pattern of killing his own people with international banned chemical weapons.
The decision to strike, after days of deliberations, marked Trump's second order to attack Syria; he authorized a barrage of Tomahawk cruise missiles to hit a single Syrian airfield in April 2017 in retaliation for Assad's use of sarin gas against civilians.
British Prime Minister Theresa May also issued a statement saying Syria's chemical attack "should surprise no-one".
"The Syrian Regime has a history of using chemical weapons against its own people in the most cruel and abhorrent way," Ms May said.
"A significant body of information including intelligence indicicates the Syrian Regime is responsible for this latest attack.
"This persistent pattern of behavior must be stopped — not just to protect innocent people in Syria from the horrific deaths and casualties caused by chemical weapons but also because we cannot allow the erosion of the international norm that prevents the use of these weapons.
"We have sought to use every possible diplomatic channel to achieve this.
"But our efforts have been repeatedly thwarted.
"Even this week the Russians vetoed a Resolution at the UN Security Council which would have established an independent investigation into the Douma attack.
"So there is no practicable alternative to the use of force to degrade and deter the use of chemical weapons by the Syrian Regime."
