Trump's apparent condemnation of the Syrian government Tuesday came less than a week after Secretary of State Rex Tillerson and US ambassador to the U.N. Nikki Haley indicated that Assad's fate would be left up to the Syrian people and that removing him from power was no longer a policy goal of the U.S.
Trump's Secretary of State, Rex Tillerson, said on Wednesday there was "no doubt" that Assad was responsible for the attack and called on Russian Federation to "really think carefully" about its continued support for the regime. It is thought to be the worst chemical weapons attack in Syria since 2013, when sarin gas was used.
Meanwhile, Dmitry Peskov, spokesman for the Russian president, said the Kremlin believes the Syrian military will do its utmost to prevent chemical agents from falling into the hands of terrorists.
"Nineteen members of my family were killed", 28-year-old Abdulhamid said in the town, surrounded by mourning relatives.
French Foreign Minister Jean-Marc Ayrault said on Thursday that "a day will come when worldwide justice will give its verdict on Bashar al-Assad who is massacring his people".
Speaking to news channel CNEWS, he added: "These crimes must not go unpunished".
Syria's foreign minister on Thursday denied regime forces used chemical weapons in a strike on the rebel-held village of Khan Sheikhun, saying Syria's armed forces "did not and will not" use chemical weapons even against jihadist groups.
US ambassador says 'no love' in dealings with Russia
She said Sunday there is "no love" between the United States and Russian Federation . Asked how he would tackle North Korea, Trump said: "I'm not going to tell you".
Senior US officials had also recently suggested it was no longer a priority that Assad be removed from power.
US President Donald Trump speaks at the White House on April 5, 2017, where he said "I will tell you, it's already happened, that my attitude towards Syria and Assad has changed very much". Western nations blamed government forces for that attack, where effects were concentrated on opposition-held areas.
This isn't the first reported use of chemical warfare in the region, nor the first condemnation from many in the global community.
The United States ambassador to the United Nations held photographs of dead Syrian children and warned the US could take unilateral action if the Security Council fails to respond, reported The New York Times.
And Britain, France and the United States have drafted a UN resolution that would demand Syria provide information on its flight operations as part of an OPCW probe.
"It is very important to try first to get out a United Nations resolution", Johnson told reporters in Sarajevo.
Syria officially relinquished its chemical arsenal and signed the Chemical Weapons Convention in 2013 to avert military action after it was accused of an attack outside Damascus that killed hundreds.
British Ambassador Matthew Rycroft dismissed that account, saying the United Kingdom had seen nothing that would suggest rebels "have the sort of chemical weapons that are consistent with the symptoms that we saw yesterday".
