A top aide to President Donald Trump on Sunday accused India of effectively financing Russia's war in Ukraine by purchasing oil from Moscow, after the U.S. leader escalated pressure on New Delhi to stop buying Russian oil.

India hasn’t given the country’s oil refiners instructions to stop buying Russian oil, according to people familiar, days after US President Donald Trump blasted New Delhi for the energy purchases.

India will keep purchasing oil from Russia despite U.S. President Donald Trump's threats of penalties, two Indian government sources told Reuters on Saturday, not wishing to be identified due to the sensitivity of the matter.
