NEW YORK, April 11 (Reuters) - Global equity markets slid on Wednesday as U.S. President Donald Trump warned Russia that missiles "will be coming," in Syria after a suspected chemical attack, and oil hit its highest in more than three years after Saudi Arabia said it intercepted missiles over Riyadh.
The fallout from new U.S. sanctions on Moscow have rattled investors and fears of military action were stoked after one of Russia's ambassadors reiterated it would shoot down any U.S. missiles fired at Syria.
Trump, who has criticized Russia for standing by Syrian President Bashar al-Assad, shot back in a message on Twitter early on Wednesday.
"Russia vows to shoot down any and all missiles fired at Syria. Get ready Russia, because they will be coming, nice and new and 'smart!'," he wrote in the post. "You shouldn’t be partners with a Gas Killing Animal who kills his people and enjoys it!"

Michael James, managing director of equity trading at Wedbush Securities in Los Angeles, said investor nerves were again rattled a day after easing on a more conciliatory tone over trade between Trump and Chinese President Xi Jinping. But one report said early talks had already broken down .
"With Xi's comments yesterday calming some of the trade war concerns, some of that optimism is going away with the concerns over what the final outcome might be over U.S. involvement over Syria," James said.
Meanwhile, oil prices hit their highest in more than three years after Trump's latest comments.
U.S. crude rose 2.43 percent to $67.10 per barrel and Brent was last at $72.50, up 2.06 percent on the day.
