A Cessna Citation XLS operated by AMREF Flying Doctors crashed into a residential area of Mwihoko in Kiambu County on Thursday afternoon, killing all four medical personnel on board—two doctors and two nurses—and two people inside a house the aircraft struck, local officials said. At least two others were taken to hospital with serious injuries. The Kenya Civil Aviation Authority said the jet, registration 5Y-FDM, departed Nairobi’s Wilson Airport at about 2:14 p.m. and lost radio and radar contact three minutes later while en route to Hargeisa, Somaliland. Kiambu County Commissioner Henry Wafula confirmed the death toll and said security forces and emergency crews quickly cordoned off the densely populated crash site. AMREF Flying Doctors chief executive Stephen Gitau said the non-profit is cooperating with investigators. The KCAA has opened a formal probe to determine why the aircraft went down shortly after take-off, and a multi-agency team from the military and police is assisting with recovery operations.
