U.N. Nuclear Agency's Board To Hold Emergency Meeting About U.S.-Israeli Strikes On Iran

Blasts in Tehran sent a huge plume of smoke into the sky in an area where there are government buildings.

The location of the meeting was not immediately clear.

A senior Israeli official told Reuters that Iran's Supreme Leader Ayatollah Ali Khamenei was killed in Israeli and U.S. strikes.

European leaders are scrambling to protect citizens and calm tensions after U.S. and Israeli strikes on Iran.

“Khamenei, one of the most evil people in History, is dead,” Trump wrote in a social media post.

Tensions have been high between the neighbors for months, with border clashes in October killing dozens of soldiers, civilians and suspected militants.
