DUBAI, United Arab Emirates (AP) — Israel’s defense minister warned Iran on Saturday that “Tehran will burn” if it continues firing missiles. Speaking after an assessment meeting with the army’s chief of staff, Defense Minister Israel Katz said that Iran will pay a heavy price for harming Israeli citizens.

Israel has begun intercepting Iranian drones outside of Israeli territory, an Israeli official said. Israel said earlier Friday that Iran launched 100 drones toward Israeli territory in response to its widespread attack on Iran's nuclear facilities and military leaders.

On Saturday, residents in Tehran reported hearing explosions, and the Iran air defense fired nonstop rounds in the Pastour neighborhood. Precise casualty figures in Iran could not be confirmed. But Iran’s U.N. ambassador, Amir Saeid Iravani, told the U.N. Security Council that Israel’s strikes in Iran had killed 78 people and injured 329 others.

Each drone carries 40-50 kg of explosives and could take up to 10 hours to reach Israel. Despite their slow speed, the sheer volume has raised alarms across the region, triggering air defenses and fears of a wider war.

Advanced espionage techniques made the most of Iranian vulnerabilities, but Israel’s ultimate aims may still be out of reach.

In response to Israel’s attack, Iran fired back with more than 100 drones. NBC News’ Chief International Correspondent Keir Simmons reports more. Former NATO Supreme Allied Commander retired Gen. Wesley Clark and Senior Fellow at the Carnegie Endowment for International Peace Aaron David Miller join Ana Cabrera to examine the possibility of further attacks.
