US President Donald Trump asserted on his Truth Social platform that Iran's nuclear sites sustained 'monumental damage' in the American attack, though a US assessment on the strikes is still underway. 'The biggest damage took place far below ground level. Bullseye!!!' he wrote.

US defence officials have said they are working to determine about just how much damage the strikes did. Iran as well has not said how much damage was done in the attack, though Tehran has not offered any details so far on the strikes it has faced from Israel in its war with that country.

Iran likely filled in tunnels at nuclear sites ahead of US strikes
