NAIROBI, Kenya — Kenya’s top prosecutor on Wednesday ordered nine businessmen and government officials charged with manslaughter for their involvement in the collapse of a dam on a rose farm that killed at least 47 people.

The prosecutor, Noordin Haji, said in a statement that his office was preparing for the defendants to be arraigned in court to answer the charges.

Among those to be charged are two managers of the commercial farm in Nakuru County in the Rift Valley, where the dam burst in May, the statement said.

Others facing charges included officials from the state-run Water Resources Management Authority, the National Environment Management Authority and the administration of Nakuru County.
