Trump-Iran news: Russia says downed US drone was in Iranian air space, contradicting key claim by Washington

Russia has military intelligence that shows a US drone was in Iranian air space when it was shot down, the secretary of Russia's Security Council has said.

Speaking at a briefing for journalists in Jerusalem, Nikolai Patrushev also said evidence presented by the US alleging Tehran was behind attacks on oil tankers in the Gulf of Oman was of poor quality and unprofessional.

Mr Patrushev's comments came after the US imposed new sanctions targeting Iran's supreme leader and other senior officials, which US president Donald Trump said was a "proportionate response to Iran's increasingly provocative actions".
