Iran will retaliate against any attack on its infrastructure, including by attacking Israel, the head of the country's supreme security agency said on Friday, as fighting between Tehran and Washington resumed this week.

"Every attack on infrastructure will be answered, and the criminal Zionist regime responsible for this atrocity will not be safe from the response of our fighters," Mohammad Bagher Zolghadr said in a statement broadcast by state television, Al Arabiya reported from AFP (10/7).

Fighting has escalated this week between the US and Iran in the most significant exchange since the two sides signed a memorandum of understanding on June 18, which aimed to formalize an April ceasefire and guide talks to end the war definitively.

The US military carried out a massive attack overnight between Wednesday and Thursday, saying it targeted 90 military sites.

However, the Mullah's State accused Washington of also targeting civilian infrastructure to divert attention from the funeral of late Supreme Leader Ali Khamenei.

Bridges and train lines between the capital Tehran and Khamenei's birthplace in Mashhad, where he was buried on Thursday, were hit, according to Iran.

In addition, Iranian authorities said 17 people were killed in the US attack.

Separately, Benjamin Netanyahu's office announced that the Israeli Prime Minister spoke with US President Donald Trump, who informed him of the latest American moves in the Gulf.

Then on Thursday night, Iranian government media reported a US-Israeli attack on a military headquarters near Bushehr, where Iran's only civilian nuclear power plant is located.

Israeli Defense Minister Israel Katz earlier said Israel was ready to resume its military campaign against Iran if necessary, and promised to do so "with greater force."
