US warns Assad's reign in Syria "coming to an end"
US Secretary of State Rex Tillerson is visiting Russia where he's expected to urge Moscow to stop supporting Assad.
His visit comes days after the US conducted missile strikes against a Syrian airbase.
Earlier, Tillerson said Syrian President Bashar al-Assad's reign was "coming to an end" and that Russia risks becoming irrelevant in the Middle East by continuing to support Assad.

Shadow of chemical attacks, missile strikes looms over Tillerson visit
Tillerson's visit to Russia comes amid simmering tensions between Washington and Moscow.
The US and its allies blame Assad's military for the chemical attack.
Russian President Vladimir Putin dismissed the US' allegations and has called for an independent UN investigation into the incident.
Is US stance on Assad changing?
Prior to the chemical attacks, the Trump administration seemed fine with allowing Assad to rule over Syria, a departure from the previous Obama administration's support for regime change.
However, missile strikes following the chemical attack along with recent statements by US officials indicate a U-turn on Trump's stance on Assad.
Yet, Trump said the US has no further plans to enter Syria's civil war.
