Our priority remains the defeat of ISIS.
UK ambassador to the United Nations Matthew Rycroft said it was "indefensible" for Russian Federation to support the Syrian regime, as UK scientists in Porton Down confirmed that samples from the scene tested positive for a toxic chemical known as sarin.
"The perspective of the United States is that the recent chemical weapons attack carried out by Syria was planned, directed and executed by Syrian regime forces".
Russian Federation has vetoed a UN Security Council resolution demanding a swift investigation into a chemical weapons attack in Syria.
"We shall see whether the current session of the OPCW executive council will lead to some more sensible and different results unlike yesterday's show which was put up by our colleagues from the United States, the United Kingdom and France in the Security Council", Ryabkov said.
Syria's Ambassador Bashar al-Jaafari said it is all "lies and accusations" against his country, and Syria no longer possesses chemical weapons, as confirmed by the United Nations in June 2014.
"We addressed that militarily".
"It is long past time for Russian Federation to stop covering for Assad ... and to push for peace", she said. "It was not a harbinger of some change in our military campaign".
In his opening remarks, Lavrov giving off the cold shoulder, stated: "I won't hide the fact that we have a lot of questions, taking into account the extremely ambiguous and sometimes contradictory ideas which have been expressed in Washington across the whole spectrum of bilateral and multilateral affairs".
Trump said Tillerson had completed a successful meeting with Putin, where "things went pretty well". We have stated our position on many occasions. So the intent was to stop the cycle of violence into an area that even in World War II, chemical weapons were not used on battlefields. "I do not know who saw them".
Authorities widen net in search for fugitive
Tips continue to flood the Rock County, Wisconsin Sheriff's Office on the possible whereabouts of fugitive Joseph Jakubowski. Jakubowski is considered "armed and dangerous" and was in possession of a bullet-proof vest and helmet, police have said.
Haley also urged the council to take action against Iran, calling the country "Assad's chief accomplice".
Until the chemical attack, the Trump administration had sought to step back from the United States position that Assad should leave power.
The White House on Tuesday accused Russian Federation and Syria of carrying out a confusion campaign over who was responsible for the chemical attack.
The Wall Street Journal cited Trump as saying that Assad's use of chemical weapons again would elicit another military response, but he also said he would not intervene in depth in the conflict.
He said the USA attack on the Syrian air base "was carried out in violation of worldwide norms".
Mattis did not clarify whether he meant the use of sarin or chlorine.
Laying bare deep and unsafe divisions on Syria and other issues, President Donald Trump declared Wednesday that USA relations with Russian Federation "may be at an all-time low".
Mr Trump also backtracked on his criticism of North Atlantic Treaty Organisation at a joint press conference with its secretary general Jens Stoltenberg, saying: "I said it was obsolete; it's no longer obsolete".
He also said the focus on defeating ISIS "remains our primary mission". While he said it was important that Mr Assad's departure "is done in an orderly way", he said "the final outcome does not provide for a role for Assad or the Assad family for the future governments in Syria".
Only weeks ago, it appeared that Trump, who praised Putin throughout the USA election campaign, was poised for a potentially historic rapprochement with Russian Federation. Russian Federation announced Friday it was cutting the line beginning Saturday morning. "It will not spiral out of control", he said.
