WASHINGTON/NEW DELHI, Aug 6 (Reuters) - U.S. President Donald Trump on Wednesday imposed an additional 25% tariff on Indian goods, citing New Delhi's continued imports of Russian oil in a move that sharply escalated tensions between the two nations after trade talks reached a deadlock.

Trump has now imposed a total of 50% tariffs on goods imported from India, and his earlier threat of levying an extra 10% for the country's membership in the Brics grouping, which includes China, Russia and South Africa as founding members, still stands.
