Iran was hit today by waves of missiles launched by Israeli warplanes, targeting areas in the capital Tehran, Isfahan, and East Azerbaijan, an important province on the country’s northwestern border.

Al Jazeera’s correspondent in Tehran, Suhaib al-Asa, suggests that Israel is trying to weaken Iran’s northwestern border front, a vulnerable front that has been heavily shelled, and has a "scenario" to insert fighters from that area or recruit agents for Israel, thereby weakening the border chain to undermine security in that region.

In this context, the Iranian Ministry of Intelligence announced that it had arrested 30 people it described as agents and spies.

Al Jazeera’s Tehran correspondent reported the arrests.

Earlier press reports spoke of U.S. and Israeli efforts to use the Iran Kurdish card in the Kurdistan Region of Iraq to destabilize security inside Iran.

The Washington Post confirmed that President Donald Trump’s administration had come to view using the Kurdish card in a war on Iran as a likely option and had contacted Iraqi Kurdish leaders to pursue that.

The Kurdistan Region hosts rear camps and bases for Iranian Kurdish opposition groups that Iran has targeted with repeated strikes in recent years, accusing them of carrying out attacks inside its territory and serving the interests of Israel and Western countries.

Officials in Erbil have repeatedly stated they reject the use of the region’s territory to launch any attacks on Iran, that they will not be a party to the war, and they have denied allegations of military movements by Kurdish opposition forces from the region toward Iranian territory.

Mutual attacks continue between the United States and Israel on one side and Iran on the other, amid threats from both sides to intensify strikes and use more lethal weapons.

Today, Tuesday, the United States and Israel carried out the "heaviest" air raids on Iran, according to the U.S. Department of Defense (the Pentagon).

The Iranian Revolutionary Guard announced it had launched the 35th wave of the "Al-Waad Al-Sadiq 4" operation against targets inside Israel, and others it described as "American" in several countries in the region.

The Revolutionary Guard confirmed the use of heavy, strategic, long-range missiles — "Khaibar, Fattah, and Qadr" — and announced that it will not use any missile whose warhead weighs less than one thousand kilograms, which signals the start of a new phase in the use of missiles.
