Israel said to have attacked Iran as explosions heard near Isfahan

US officials have told several news outlets that an Israeli missile has struck Iran on Friday morning, as Iran confirmed explosions were heard in Isfahan and activated air defences.

Flights can be seen diverting from Iran's airspace and the country suspended flights to and from several cities, including Isfahan.

On its end, Iran has so far said that it shot several drones, saying there was "no missile attack for now".

Several Iranian nuclear sites are present in Isfahan, but local media says the facilities are "completely secure."

Israel reportedly notified the US prior to launching this attack, which was a retaliation for Iran's unprecedented barrage of drones and missiles on Israel on 13 April.

The Iranian assault was itself a response to the reported Israeli strike on the country's consulate in Damascus, Syria, which killed several people, including top Iranian commanders.

The Israeli military have so far refused to comment on the latest incident.
