Five explosions were reported heard across Tehran and the nearby city of Karaj early on Saturday morning, according to Iranian media, in what is alleged to be the beginning of an Israeli retaliatory attack on Iran.

A second wave of airstrikes was reported following blasts heard in Shiraz later on early Saturday morning.

I don't immediately know what the significance of those locations are, and there's probably more-detailed information coming shortly, but I imagine that that alone is probably enough to give people who have been looking at the matter an idea of what likely targets were.

EDIT: Oh, wait, missed this bit (or it was added after I initially read the article):

Israel reportedly attacked the location of the headquarters of the Islamic Revolutionary Guards Corps in Iran.

Several of the strikes in Tehran targeted military bases across southern and southwestern Tehran, according to Iranian media.

Reports of explosions at the Imam Khomeini International Airport in the Iranian capital were also received, however Iranian officials denied anything was wrong.

EDIT2: Yeah, apparently they've been updating the article, whether or not that bit was already there.

EDIT3: I didn't look at what-all was known about the intended targets of the Iranian ballistic missile strike a while back, but I do recall that it included Israeli airbases and Mossad's headquarters. Hitting the IRGC headquarters and Iranian airbases would be analogous, I suppose, so that'd make sense if Israel's intent is to have an attack that mirrors the targets of the Iranian attack.

EDIT4: An anonymous Israeli military source was quoted on CNN's liveblog as saying that no energy targets were attacked, only military.

EDIT5: Israel's foreign ministry also announced on Twitter (and probably elsewhere) that they were striking military targets, and I'd take that as more authoritative than whatever anonymous source CNN had.

EDIT6: Barrons reports that "Iran State TV Says At Least Six Blasts Heard Around Tehran", so I guess that gives an idea as to scope.

EDIT7: This has some information as to attack composition:

https://jpost.com/middle-east/iran-news/article-826126

Over 100 planes were involved in the attack on Iran on Saturday, including the cutting-edge F-35.

Israel’s preliminary strike on radar targets in Syria was aimed at “blinding” Iran’s capabilities, quickly escalating into an offensive targeting Tehran and Karaj, Iran’s capital and another strategic location.

The IDF confirmed the operation focused strictly on military targets, steering clear of nuclear and oil facilities to prevent wider conflict escalation. High alert remains as Israel anticipates potential retaliation, not only from Iran.

This large-scale assault involved over 100 aircraft, including F-35 “Adir” stealth fighters, covering approximately 2,000 kilometers. According to foreign reports, strikes focused on Tehran and Karaj, with the IDF stating that each wave targeted military sites exclusively, mitigating further conflict risks.

EDIT8: CNN reports that Israel says that the attack is complete.

How many military orphanages, military preschools and military press tents are they planning to strike this time? Are military supermarkets, military food banks and military temples also on the target list, or not this time?

I hope that both countries now are aware of the damage they could cause to each other. Israel can overwhelm Irans air-defense with their stealth bombers. Iran can overwhelm Israels missile defense with barrages of ballistic missiles.

Even before the nuclear escalation level they both can inflict very serious damage to each other and their respective defense systems are not able to prevent attacks, only mitigate some of it.

I am looking forward to the price calculations for this one. For the Iranian missile attack 01. October iirc. the damage was considered to be in the range of $ 50 Mio. With the Iranian missiles supposedly costing around $ 100k each, that would be about $ 20 Mio. For the attack i couldn't find Israels interceptions costs. For the April attack it was sought to be around $ 550 Mio. So i would expect the October interception to have cost at least similarly. $ 600/20 Mio. is a 30 to 1 ratio.

Sending F-35s long ways is expensive, but with the more precise strikes that could have inflicted substantial damage at key points.

Just after the markets close, Monday is gonna be interesting

Sounds like they hit some missile manufacturing facilities. Hopefully they also hit some drone facilities.
Less missiles and drones for Russia's attacks on Ukraine and for the Iranian militias' attacks on the Kurds in Syria and Iraq.

Edit: Seems like they did also hit drone facilities. Less Shahed drones for Russia.
