A six-story residential building collapsed in heavy rain in Nairobi, killing 10 people and injuring at least 134, Kenyan officials said Saturday. Interior Minister Joseph Nkaissery confirmed the deaths. The Kenya Red Cross said 150 building units and adjacent homes were affected. Rescuers said they could hear voices of five people trapped in the building and said it will be difficult to remove the concrete slabs using heavy machinery without endangering those stuck in the rubbled, AP quoted nominated legislator Johnson Sakaja as saying.
