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.

Indian officials confirmed Saturday the country is not altering policy and will continue buying oil from Russia, despite threats of a financial "penalty" from U.S. President Donald Trump.

There has been no official indication yet if India will stop buying oil from Russia. However, Indian government sources said that India will keep purchasing oil from Russia, and there would be no immediate changes.
