Trump Claims 'Monumental Damage' To Iranian Nuclear Sites

US President Donald Trump has claimed "monumental damage" was caused to the Iranian nuclear sites by Washington's overnight strikes on Tehran, media reports said. However, some independent experts analyzing commercial satellite imagery have been quoted by NPR saying the nation's long-running nuclear enterprise is far from destroyed.

In a post on Truth Social, the President claimed, "Monumental Damage was done to all Nuclear sites in Iran, as shown by satellite images. Obliteration is an accurate term!

"The white structure shown is deeply embedded into the rock, with even its roof well below ground level, and completely shielded from flame. The biggest damage took place far below ground level. Bullseye!!!"

Trump on Saturday announced bombing Iran's three nuclear sites and said that with this operation, there would either be peace or more tragedy for Tehran.

The sites are Fordow, Natanz, and Esfahan.

Iran-Israel Conflict

The conflict started a week ago when Israel launched airstrikes against Iranian nuclear and military sites, primarily targeting uranium enrichment facilities to prevent Iran from developing nuclear weapons.

Iran and Israel have been trading missiles and drones at each other since the conflict between the two Middle Eastern countries began recently.

The war began when the Israeli military launched "Operation Rising Lion" and attacked Iranian cities, saying it had concluded Tehran was on the verge of developing a nuclear weapon.
