Iran has grounded commercial flights across parts of the country after reports of explosions.

State media also said Iran fired its air defence systems after reports of blasts near the city of Isfahan.

It remained unclear if the country was under attack.

But tensions remain high in the wider Middle East after Iran’s missile and drone attack on Israel over the weekend.

The Israeli military did not immediately respond to a request for comment, AP reported.

Iran’s state-run IRNA news agency said its air defences fired across several provinces – but did not elaborate on what caused the batteries to fire.

State television noted a “loud noise” in the area.
