U.K.'s Boris Johnson cancels Moscow trip over Syria

British Foreign Secretary Boris Johnson canceled a planned trip to Russia after he said developments in Syria changed the situation "fundamentally."

Johnson was set to travel to Moscow on Monday, but decided to cancel the trip stating that "developments in Syria have changed the situation fundamentally."

His decision came after United States President Donald Trump ordered the firing of 59 Tomahawk cruise missiles into a west Syrian airfield believed to be the source of a deadly chemical attack this week that killed and injured hundreds of men, women and children.

Johnson said his priority was to continue contact with the United States and other countries to provide international support for a ceasefire in the days leading up to the G7 meeting on April 10 and 11, UPI reports.

He said he planned to gather a group of other "like-minded partners" in order to "explore next steps soon."
