What happened
The collapse is the latest in a string of construction accidents in Kenya. Police disaster-management chief Duncan Ochieng gave the toll and the site figures at the scene, and the Kenya Red Cross placed the collapse in Syokimau, near the SGR terminus area on the Nairobi–Mombasa side of the capital.
It comes three weeks after a building under construction collapsed in Eastleigh, Nairobi, on 23 October, where police put the toll at eight. That is a separate event, covered on its own page.

Why it matters
Building collapses have become a repeated killer in Kenya's fast-growing capital region. With 24 collapses recorded in 2026 before this one, the Syokimau deaths keep the pressure on regulators, counties and builders over workmanship, materials and supervision.
