Moscow is rushing to the support of its ally amid a joint US-Israeli bombing campaign

Russia is providing Iran with intelligence to help target US forces in the Middle East, according to a report, in a development likely to cause a rift between Donald Trump and Vladimir Putin.

Since the beginning of the war last Saturday, Moscow has been supplying Iran with the locations of US military assets, including warships and aircraft, three officials told The Washington Post.

The conflict has already spread far beyond the Middle East as Iran retaliates against US bases in the region, with attacks reported as far as Azerbaijan and Sri Lanka.
