United States envoy Nikki Haley says Syria regime change is 'inevitable'

Dozens of people including at least ten children have been killed and more than 200 injured in a suspected chemical attack in northern Syria multiple activist groups claim

The Kremlin says Russian President Vladimir Putin does not plan on meeting with Secretary of State Rex Tillerson when he visits Moscow on Wednesday. Still, Haley said the USA didn't see a peaceful future for Syria with Assad in power. During an interview on CBS Sunday, he said destroying ISIS was Trump's top priority.

Efforts to reach an agreement on statements and strategy ahead of time - a normal part of pre-meeting G7 diplomacy - has gone very slowly, partly because of a hard transition at the US state department, where many key positions remain unfilled.

He says of the recent chemical attack: "We can not let this happen again".

Yet the US has sent mixed messages about what it wants in the short term; it's not even clear whether Washington intends to help oust Assad. Putin said on Tuesday he believed Washington planned to launch more missile strikes, and that rebels were planning to stage chemical weapons attacks to provoke them.

The meeting in the Tuscan walled city of Lucca brings together the foreign ministers of France, Germany, Britain, Japan and Canada - as well as the USA and current G-7 president Italy.

A spokeswoman for the prime minister said Trump had thanked May for her support following last week's USA military action in Syria against the Assad regime.

In a shift in Washington's strategy, USA missiles hit a Syrian air base last week in retaliation for what many say was a poison gas attack by Syria's military in which scores of civilians died.

Mattis says he trusts Assad regrets last week's chemical weapons attack, given the USA retaliatory strikes. While Britain says Assad must go, Alfano was cautious on the issue, saying that decision should be up to the Syrians.

The United States has made a preliminary conclusion that Russian Federation knew in advance of Syria's chemical weapons attack last week, but has no proof of Moscow's involvement, a senior US official said Monday.

"Russia must fully honour the commitments it made on Syria, Ukraine, and the Intermediate Range Nuclear Forces Treaty, and other topics of global concern".

"I will tell you: ... if you gas a baby, if you put a barrel bomb into innocent people, I think you will see a response from this president", Spicer said. Instead, the United States is hoping to use the visit - the first by a Trump Cabinet official to Russia - to convey its expectations to Moscow and then allow the Russians a period of time to respond.

U.S. Secretary of State Rex Tillerson says Russian Federation must choose between aligning itself with the U.S. and likeminded countries or embracing Syrian President Bashar Assad, Iran and the militant group Hezbollah.

"Russian Federation has been a staunch backer of Assad during the country's civil war, and Peskov said Monday that it would not abandon that support".

As he prepared to leave for Moscow, Mr Tillerson said: "It is clear to all of us that the reign of the Assad family is coming to an end".

Up until the chemical attack, Trump had said Washington would no longer act as the world's guardian, especially if it was not in the interest of the United States.

The visit also comes amid an FBI investigation into whether Russian Federation potentially colluded with Trump's campaign to influence the US election.

US presidents have a tradition of entering office and expressing hope for improved relations with Russian Federation.

Tillerson traveled Tuesday to Moscow.

Also speaking at Monday's ceremony, Federica Mogherini, European Union foreign-policy chief, said "there is no military solution to this war and the negotiations in Geneva must start again with the support of all of us: Europe is the one which is trying to get the Syrians to sit at the same table".
