A Fox News journalist was forced to run for cover live on air after Iran began bombing Israel while he reported from Tel Aviv. Trey Yingst, who is the network’s chief foreign correspondent, was forced to cut short his broadcast after ballistic missiles filled the sky over the Israeli city Friday night.

Yingst stood on a balcony while Israel’s famed Iron Dome weapons defense system began to intercept some of the enemy fire. But a few moments later it became clear that Yingst and his crew were in danger as the barrage of missiles continued and smoke filled the skies.

It came as Israel sent an urgent warning that ‘dozens of Iranian ballistic missiles’ are headed to the nation, with footage showing some appeared to slip past the Iron Dome in Tel Aviv. Iran’s Supreme Leader Khamenei said in a furious address overnight that ‘life will be dark’ for Israel after it decimated Iran’s nuclear sites and top military officials.

Earlier today, Tehran vowed ‘painful revenge’ for Israel’s actions, and state media reported hundreds of missiles were fired at Israel Friday night. In a statement from the Iranian Revolutionary Guard Corps shortly after missiles hit Israel, the nation’s military said it struck dozens of targets ‘forcefully and with precision.’

After a first round of missiles struck Tel Aviv, the Israeli military said more cities are under threat of being hit, with ‘another barrage of dozens of missiles fired at Israel.’ Smoke could be seen filling the skies over Tel Aviv, as residents were told to urgently seek bomb shelters.

An Israeli military official told the New York Times that at least seven sites were hit in Tel Avid. It is unclear how many Israeli cities in total have been targeted or hit, with some reports that Jerusalem was also targeted.

Officials have not yet said if there are any casualties. The barrage of missiles from Iran came in retaliation to Israel’s attacks on Iranian targets including nuclear sites overnight.

Israel killed a number of Iran’s top military and nuclear officials in the strikes, which prompted a furious response from Iran’s supreme leader, Ayatollah Ali Khamenei. In a televised statement on Friday night, he declared that Israel ‘should not think they have attacked and it’s over.’

‘Life will be dark for them,’ Khamenei said. ‘They started it, they started a war. We will not allow them to escape this big crime unharmed. Iran’s armed forces will definitely be striking hard.’ Tehran vowed ‘painful revenge’ for Israel’s unprecedented offensive overnight that has left the region teetering on the brink of all-out war.

An Israeli military spokesman has said their ‘defense systems are working to intercept the threat’ that has arrived in their airspace after being launched this afternoon. Citizens are still being urged to go to their nearest bomb shelter as hundreds of ballistic missiles rain down on the city. Israel’s defense minister, Israel Katz, said in a statement after missiles hit Tel Aviv around 9pm local time that Iran ‘crossed a red line’ by hitting civilian areas.
