Israel says, as well as the Ayatollah, it has taken out several of Iran's top commanders in the strikes, while the U.S.

says it targeted strategic infrastructure.

It's not known how many civilians have been killed nationwide.

But in the southern town of Minab, explosions from Israeli missiles killed more than 80 people, according to Iranian state media, which also says many of the dead are children.

Video on state media shows panicked parents sifting through the rubble while others stand frozen, staring at the still-smoking building.

Iran's response to the nationwide attacks came swiftly.

Retaliatory strikes from Iran sent waves of sirens through Jerusalem and Tel Aviv, where Israelis sheltered underground, as explosions rocked the streets above.

Missiles seen too over Doha, Bahrain and Dubai, most of which were intercepted.

So just how capable is Iran of waging a full-on war with the US and Israel?

Well, Iran has several proxy fighters that it supports in the region, which it could mobilize.

The leader of the Houthis in Yemen, Abd al-Malik al-Houthi, says they stand in solidarity with Iran and is fully prepared for any developments, framing the moment as the entire Islamic world being under attack.

Over in Iraq, which is home to several armed groups backed or directly trained by Iran's Revolutionary Guard, protesters voiced their anger over the US and Israeli strikes.

While Russia, one of Iran's most powerful supporters, told an emergency meeting of the UN Security Council that Tehran was willing to engage in diplomacy.

but instead has been stabbed in the back.

Moscow has not, however, offered military assistance so far.

Iran itself has significant military capabilities, including a growing fleet of attack drones, but its conventional air force and navy are no match for American or Israeli firepower.

and its ability to sustain a prolonged conflict is sharply constrained by its economy.

Years of international sanctions have severely weakened Iran's economy and constrained its growth.

Plus there's the domestic strain.

Iran has faced repeated waves of anti-government protests in recent years over inflation, unemployment and political repression, unrest that has been met with force but has never fully subsided.
