Three workers killed as a perimeter wall collapses at a Riverside excavation site in Nairobi, police say
Three workers were killed when a perimeter wall collapsed on Saturday morning at a construction site in Riverside, Nairobi, that was still at the excavation and foundation stage, Nairobi police boss Issa Mohamud said. The county government said 39 workers were recorded at the site; eleven were rescued alive with severe injuries and taken to hospital, fourteen were accounted for and confirmed safe, and rescue teams were still working to establish the whereabouts of the others. The collapse came a day after six workers died in a building collapse at Syokimau.

What happened
The wall gave way at about 11:30am on Saturday at a property undergoing excavation near Grand Residence in Riverside. Preliminary assessments said the main building was still at the excavation and foundation stage, with no upper floors erected.
Workers at the site began searching the rubble themselves alongside emergency teams, and the area was cordoned off as multi-agency rescue operations continued.
