Trump threatens harsh Russia tariffs if Ukraine war continues beyond 50 days

US President Donald Trump on Monday threatened "severe tariffs" against Russia if Vladimir Putin does not agree to a ceasefire with Ukraine in the next 50 days.

We're going to be doing secondary tariffs. If we don't have a deal in 50 days, it's very simple. And they'll be at 100 percent, and that's the way it is," Trump said while speakign to reporters at the White House on Monday.

Trump also said that the Patriot missile systems and batteries will be among the weapons the US would send to Nato to support Ukraine in its war against Russia.

It's a full complement with the batteries," news agency Reuters quoted Trump as saying.

We're going to have some come very soon. Within days, a couple of the countries that have Patriots are going to swap over and will replace the Patriots with the ones they have," he added.
