US President Donald Trump is set to be briefed by Israel's Prime Minister Benjamin Netanyahu that any expansion of Iran's ballistic missile program poses a threat that could necessitate swift action, NBC News reported on Saturday.
Israeli officials are concerned that Iran is reconstituting nuclear enrichment sites the US bombed in June, and are preparing to brief Trump for options on attacking the missile program again, the NBC report added.
Reuters could not verify the report.
New satellite imagery shows recent activity at the Natanz nuclear facility that was damaged during June's 12-day war with Israel, according to the US-based Institute for Science and International Security (ISIS).
During the June conflict, the IAEA confirmed Israeli strikes hit Iran's Natanz underground enrichment plant.
The think tank said the satellite imagery from December 13 show panels placed on top of the remaining anti-drone structure at the Pilot Fuel Enrichment Plant (PFEP), providing cover for the damaged facility.
It suggested the new covering allows Iran to examine or retrieve materials from the rubble while limiting external observation.
The Natanz uranium enrichment facility, located some 250 km south of the Iranian capital Tehran, is one of Iran's most important and most controversial nuclear facilities in the Middle East.
