The US has observed Iran moving military equipment, including drones and cruise missiles, around the country, signalling that it may be preparing to attack Israeli targets from within its own territory, two intelligence officials told CNN reporters.
However, it is not clear whether Iran is preparing to strike from its soil as part of an initial attack, or whether it is posturing to try to deter Israel or the US from a possible counterstrike on its territory.
One of the intelligence officials said the US had observed Iran preparing as many as 100 cruise missiles.
