TEL AVIV, Israel (AP) 鈥 Israel attacked military targets in Iran with pre-dawn airstrikes Saturday in retaliation for the barrage of ballistic missiles the Islamic Republic fired on Israel earlier this month. It was the first time Israel鈥檚 military has openly attacked Iran.

The Israeli military said its aircraft targeted facilities that Iran used to make the missiles fired at Israel as well as surface-to-air missile sites.

Crucially, there was no indication that Iran鈥檚 oil or nuclear sites were struck. Iran insisted the strikes caused only 鈥渓imited damage,鈥 and Iranian state-run media downplayed them. Taken together, the moves suggested at least for now that both countries are trying to avoid a more serious escalation.

Still, the strikes risk pushing the archenemies closer to all-out war at a time of , where militant groups backed by Iran 鈥 including and 鈥 are already .

Following the airstrikes, Iran鈥檚 Foreign Ministry issued a statement saying it 鈥渃onsiders itself entitled and obligated to defend against foreign acts of aggression. Foreign Minister Abbas Araghchi said Iran has 鈥渘o limits鈥 in defending its interests.

But late Saturday, Iran's military issued a carefully worded statement suggesting any cease-fire in Israel's ground offensives in Gaza and Lebanon would trump any possible retaliatory strike.

Iran's state-run IRNA news agency said four people were killed, all with the military air defense. Iran鈥檚 military said the strikes targeted military bases in Ilam, Khuzestan and Tehran provinces. But Iran鈥檚 paramilitary Revolutionary Guard was silent.

U.S. President Joe Biden told reporters Israel gave him a heads-up before the strikes and said it looked like 鈥渢hey didn鈥檛 hit anything but military targets.鈥 His administration won in mid-October that it would not hit nuclear facilities and oil installations.

鈥淚 hope this is the end,鈥 Biden said.

Israel's first open attack on Iran

Iran hadn鈥檛 faced a sustained barrage of fire from a foreign enemy since its 1980s war with Iraq. Explosions could be heard in Tehran until sunrise.

Israel is also widely thought to be behind a near a major air base in Iran that hit the radar system for a Russian-made air defense battery. Iran had earlier at Israel, causing , after two Iranian generals were killed in an apparent Israeli airstrike on an Iranian diplomatic post in Syria.

On Oct. 1, Iran launched at least 180 missiles into Israel in retaliation for Israel landed against Hezbollah. They caused minimal damage and a few injuries. Prime Minister Benjamin Netanyahu said Iran 鈥渕ade a big mistake.鈥

鈥淚ran attacked Israel twice, including in locations that endangered civilians, and has paid the price for it,鈥 Israeli military spokesperson Rear Adm. Daniel Hagari said. He added: 鈥淚f the regime in Iran were to make the mistake of beginning a new round of escalation, we will be obligated to respond.鈥

Images released by Israel鈥檚 military showed members preparing to depart for the strikes in American-made F-15 and F-16 warplanes.

The Iranian military statement described Israel's warplanes as firing lightweight missiles at a distance of 100 kilometers (62 miles) from the Iranian border. The missiles struck air defense radar stations, the military said, some of which were already under repair.

However, Iran's paramilitary Revolutionary Guard 鈥 which oversees its vast arsenal of ballistic missiles 鈥 remained silent, raising questions about whether anything had been hit at its bases. The Guard is one of the main power centers in Iran's theocracy, as the regular military has been shunted aside since the 1979 Islamic Revolution.

Israel鈥檚 attack did not take out highly visible or symbolic facilities that could prompt a significant response from Iran, said Yoel Guzansky, a researcher at Tel Aviv鈥檚 Institute for 春色直播 Security Studies who formerly worked for Israel鈥檚 春色直播 Security Council.

It also gives Israel room for escalation if needed, and targeting air defense systems weakens Iran鈥檚 capabilities to defend against future attacks, he said, adding that if there is Iranian retaliation, it should be limited.

Israel has again shown its military precision and capabilities are superior to Iran's, said Sanam Vakil, the director of the Middle East and North Africa program at the London-based think tank Chatham House.

鈥淏y targeting military sites and missile facilities over nuclear and energy infrastructure, Israel is also messaging that it seeks no further escalation for now," Vakil said. "This is a sign that the diplomacy and back-channel efforts to moderate the strike were successful.鈥

After the strikes, the streets in Iran's capital were calm, and children went to school and shops opened. There were long lines at the gas stations 鈥 a regular occurrence when military violence flares as people stock up. But some residents seemed anxious and avoided conversations with an Associated Press reporter.

Mixed reactions at home and abroad

Israeli opposition leader Yair Lapid criticized the decision to avoid 鈥渟trategic and economic targets," saying on X that 鈥渨e could and should have exacted a much heavier price from Iran.鈥

The United States warned against further retaliation, and Britain and Germany said Iran should not respond. 鈥淎ll acts of escalation are condemnable and must stop,鈥 the spokesman for the U.N. secretary-general said.

Saudi Arabia was one of multiple countries in the region condemning the strike, calling it a violation of Iran's 鈥渟overeignty and a violation of international laws and norms.鈥 Hezbollah and Hamas condemned Israel's attack.
