U.S. Secretary of State Rex Tillerson has arrived in Moscow to meet with Russian officials about the Syria civil war.

It's the first official trip to Russia by a member of President Donald Trump's Cabinet.

Russia has been incensed by U.S. allegations of complicity in Syrian President Bashar Assad's use of chemical weapons. The U.S. increased the pressure Monday when a senior official said the U.S. has made a preliminary conclusion that Russia knew in advance of Syria's chemical weapons attack last week.

The visit also comes amid an FBI investigation into whether Russia potentially colluded with Trump's campaign to influence the U.S. election.

Tillerson plans to meet Wednesday with Russian Foreign Minister Sergey Lavrov. It's unclear whether he will also meet with Russian President Vladimir Putin.

President Vladimir Putin says Russia will appeal to the United Nations to investigate last week's chemical attack in Syria.

Moscow has dismissed suggestions that the Syrian government that it backs could be behind the attack in Idlib province.

Putin also said Russia has received intelligence about planned "provocations" using chemical weapons that would put the blame on the Syrian government.

Russia has defended Bashar Assad's government which has been accused of launching a chemical weapons attack on the Idlib province.

Russia's foreign ministry says it hopes for "productive talks" with U.S. Secretary of State Rex Tillerson, as Tillerson heads to Moscow in his first visit to Russia as the top U.S. diplomat.

The ministry said in a three-page statement issued ahead of Tillerson's arrival later on Tuesday that the outcome of the talks is important not only for the Russia-U.S. ties but "for the overall atmosphere on the world stage."

Tillerson is traveling to Russia several days after a chemical attack in Syria and a U.S. air strike on a Syrian government base that Moscow on Tuesday dismissed as "an act of aggression." Moscow is a staunch ally of President Bashar Assad whom the United States blamed for the chemical attack.

Tillerson said Tuesday that Russia must choose between aligning itself with the U.S. or with Assad and Iran.

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

Tillerson says it's unclear whether Russia failed to take seriously its obligations in Syria or has been incompetent. But he says that distinction "doesn't much matter to the dead."

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

Tillerson says the U.S. sees no future role for Assad in Syria, but he says the U.S. isn't pre-supposing how Assad's departure will occur.

Tillerson is traveling Tuesday to Moscow. He says Russia can play a role in Syria's future but that aligning with Assad won't serve Russia's long-term interests.

The entry timed 8:50 a.m. has been corrected to say that Tillerson is meeting Lavrov on Wednesday, not Putin.
