Syria war: G7 seeks united front on Assad and Russian Federation

But the cancellation of tomorrow's meeting, which came after discussions with US Secretary of State Rex Tillerson, led to him being criticised as "Washington's poodle", an attack dismissed by the Foreign Office.

Syria's ally Russian Federation says the deaths were caused when a Syrian air strike hit a depot where rebels were making chemical weapons, leading to a leak of toxic gas.

Like Trump, the Obama team was not trying to topple the Assad regime and was not intending to address Assad's use of conventional weapons to kill civilians.

Critics accused him of being "Washington's poodle" after the trip was cancelled following discussions with U.S. secretary of state Rex Tillerson, who will go ahead with a planned trip to Russian Federation to "deliver that clear and co-ordinated" message to the Kremlin. "You pick and choose your battles and when we're looking at this, it's about changing up priorities and our priority is no longer to sit there and focus on getting Assad out", Haley told reporters on 30 March.

Johnson called on Russian Federation, a key Assad ally, "to do everything possible to bring about a political settlement in Syria and work with the rest of the global community to ensure that the shocking events of the last week are never repeated". "The failure related to the recent strike and the recent awful chemical weapons attack in large measure is a failure on Russia's part to achieve its commitment to the worldwide community", he added.

Mr Trump's about-face to intervene in the Syrian civil war has put the U.S. and Russian Federation at loggerheads and jeopardises Mr Trump's ambition to team up with Vladimir Putin to eradicate the Islamic State militant group in Iraq and Syria.

North Korea's Ministry of Foreign Affairs, meanwhile, said the USA strikes on the air base "can never be tolerated" and were a "clear act of invasion against a sovereign country", the communist government's news arm reported.

Haley told CNN's "State of the Union" that removing Assad was now a U.S. priority.

June 23, 2014: The Organization for the Prohibition of Chemical Weapons says it has removed the last of the Syrian government's chemical weapons. "The United States military was not built to conduct pinprick attacks", he said in late 2015.

The Syrian forces resumed flight operations at the airbase that was hit by the United States on Friday, an opposition group said. Idlib's rebel population has swelled in recent months, due largely to a series of agreements with Damascus allowing rebels safe passage to the province from other areas of the country.

The opposition says Assad is forcibly displacing his opponents to remote parts of Syria in deals that offer rebels safe passage out, calling it a policy of demographic change.

Assad, in an interview before the USA attack, made clear that so-called local "reconciliation" agreements remain central to his strategy, along with military action.

Alfano said the site of past Nazi atrocities was a reminder that "peace is not a given".

There is no "option but victory", he said.
