After Israeli Defence Minister Israel Katz announced the strike, US President Donald Trump confirmed Washington’s involvement in the operation, which reportedly hit five Iranian cities, including the capital, Tehran.

Several missiles struck the University Street and Republic areas of Tehran, according to reports citing local media.

Iran’s state-run news agency IRNA reported thick smoke rising over parts of the capital, with explosions heard at multiple locations.

According to media reports, Iran’s Supreme Leader Ali Khamenei has been moved to a secure location following the strikes.

In a video address, Trump said the United States would not allow Iran to develop nuclear weapons and added that diplomatic efforts had previously been made to reach an agreement.

Calling the operation a “noble mission,” Trump acknowledged the possibility of casualties, saying the action was aimed at securing long-term peace and stability.

Israel has also declared a state of emergency in anticipation of possible retaliatory strikes from Iran, raising fears of wider regional escalation.
