The members of Kenya's security forces who shot dead anti-tax protesters at the country's parliament last June have been identified by the BBC. The BBC's analysis of more than 5,000 images also shows that those killed there were unarmed and not posing a threat. The East African nation's constitution guarantees the right to peaceful protest, and the deaths caused a public outcry.

Despite a parliamentary committee ordering Kenya's Independent Policing Oversight Authority (IPOA) to investigate the deaths on the streets of the capital, Nairobi – and make public its findings – no report regarding the killings at parliament has yet been issued and no-one has been held to account. The BBC World Service team analysed videos and photos taken by protesters and journalists on the day. We determined when each was taken using camera metadata, livestream timings and public clocks visible in the shots.

We plotted three of the killings on a 3D reconstruction of Kenya's parliament, allowing us to trace the fatal shots back to the rifles of a police officer and a soldier. What follows is BBC Africa Eye's detailed timeline of events as Kenya's MPs entered parliament for the final vote on the government's controversial finance bill, while protesters amassed on the streets outside on Tuesday 25 June 2024.

"It was a beautiful party," says prominent human rights activist Boniface Mwangi, who was there. "Kids came out with Bluetooth speakers and their water. It was a carnival."
