Data analysed by the British public broadcaster reveals the scale of destruction in Tehran since the start of the war between the United States and Israel. Over the past four weeks, Israel has dropped 3,600 munitions on the Iranian capital, striking nearly 40 police stations and bases linked to the Basij paramilitary force, many of them located in residential neighbourhoods.

Investigators gathered eyewitness accounts, verified social media footage and reviewed satellite imagery to document the aftermath of the attacks. Residents described widespread devastation, with families caught in the blasts and homes reduced to rubble.

The programme also features other global stories, including rare footage of sperm whales supporting a female during birth, the swearing in of a former rapper as Nepal's prime minister, and a mother’s struggle to manage her young son's screen time.
