A mother stands by the rubble, crying out for her daughter.

For days she has been waiting for rescue workers to dig through the flattened remains of what was once her daughter's flat in Resalat, a residential district in eastern Tehran.

They don't have the manpower to get her out, the woman says.

My daughter is under the rubble... she's afraid of the dark.

For a month, Iran has been at war with the U.S. and Israel, which have been carrying out strikes across the country at targets linked to the regime.

But these attacks are also having a devastating impact on civilians living nearby.

They are now being caught between bombardment from the skies and a repressive regime that responded to anti-establishment protests with a deadly crackdown in January.

Since the start of the war, BBC Eye has gathered exclusive footage from independent journalists inside Tehran.

The BBC is rarely allowed into Iran and has not been given access since the war began.

We've gathered eyewitness testimony, filmed the aftermath of strikes and analysed footage from social media and satellite imagery.

Our analysis shows there has been a series of attacks on state-linked targets that are embedded in civilian neighbourhoods in Tehran, with deadly consequences for those living around them.

Dozens of families had lived in the multi-storey apartment building in Resalat before it was destroyed by an Israeli air strike on 9 March.

The daughter trapped in the rubble had been living in the complex with her husband and own young daughter.

Days after the strike, she and her daughter were found dead under the rubble. The husband survived.

Local authorities and residents say between 40 and 50 people were killed in this single attack.

Those made homeless are currently staying at a hotel nearby.

This was our life, said a resident, lamenting the loss of his belongings and home.

Military experts suggest that the scale of destruction and use of large bombs point to an escalating conflict with dire implications for civilians.

The United Nations has called for restraint in the use of powerful weapons in populated areas, emphasizing the need to protect civilian lives.

As airstrikes continue, residents in Tehran face uncertainty and fear with no clear guidance on safety measures from their government.
