Iran's hope for a deal with the US is keeping it from going 'nuclear' and destabilising energy markets, experts say

TEHRAN - Iran condemned Israel's attack on a state TV building in Tehran on Monday as a "war crime", and called on the UN Security Council to take action. The strike on the offices of IRIB during a live broadcast was a "wicked act" and a "war crime", said foreign ministry spokesman Esmaeil Baqaei.

Since Israel began its concerted attack on Iran on Friday, calls for regime change in Iran have grown louder – from hawks in the US Congress to Israeli officials and some Iranian activists abroad.

The conflict between Israel and Iran has forced many countries in the Middle East to close their airspace, as Israeli jets and Iranian exploding drones and missiles fly over their night skies.

Israel’s campaign, militarily and rhetorically, has quickly evolved beyond its initial targets. Over the weekend, it hit Iran’s energy facilities, including a gas depot and an oil refinery, triggering huge fires and spewing smoke across the sprawling capital of about ten million people.

Further strikes from Iran on Israel have left many people killed and dozens injured as the fiery war between the two nations continues. Iran's parliament announced it was preparing a bill that would see exit from the Nuclear Non-Proliferation Treaty as the Israeli military said it has destroyed a third of Iran's surface-to-surface missile launchers.

A family whose home was damaged by Israeli airstrikes recounted the moment their neighboring building was hit while they were asleep. Iran and Israel have traded unprecedented air and missile strikes,

But Israel's formidable and sophisticated military forces - with an arsenal largely, but not exclusively, provided by the United States - are enabling it to overpower a much larger enemy. The BBC looks at the military balance in the latest war in the Middle East.
