US officials say Russia is providing Iran with intelligence on the locations

of US warships and aircraft in the Middle East,

helping Tehran identify and potentially strike US forces in the region.

The information reportedly includes the positions of US ships, aircraft and radar systems.

US officials say this support suggests that Russia may

be indirectly involved in the conflict, although Moscow

has not commented on these claims and is not directly involved in the fighting.

Meanwhile, according to the same officials,

China does not appear to be providing similar assistance to Iran.
