US stock futures fell as President Trump threatened stiff tariffs on imports from more than a dozen countries and delayed the return of sweeping April levies.

Futures on Wall Street are extending losses after benchmark indices witnessed selling pressure at the start of the new trading week. The Dow futures are currently down 110 points, while those on the S&P 500 and Nasdaq are down 15 and 25 points respectively.
