NAIROBI , Kenya ( CNN ) -- A plane crashed Tuesday in western Kenya , killing all four people on board , including a Cabinet minister and an assistant minister , President Mwai Kibaki said . The two senior government figures were members of Raila Odinga 's party . `` The wreckage has been found and there are no survivors , '' Kibaki said , according to the government Web site . Kenyan Roads Minister Kipkalya Kones and Assistant Minister of Home Affairs Lorna Laboso had been on board the Cessna 210 , which was headed to Kericho , in the Rift Valley . The plane crashed in a remote area called Kajong ' a , in western Kenya , Kibaki said . The president identified the two others killed as Kenneth Kiprono Bett , who worked for Kones , and the pilot . `` Our country has lost leaders of immense potential at their prime age and with a promising future , '' Kibaki said . `` Let us all remain united at this moment of sorrow as a nation . '' Salim Lone , a government spokesman , told CNN earlier that the plane crashed about an hour after it took off from Nairobi 's Wilson Airport around 2:18 p.m. local time ( 7:18 a.m . ET ) . `` This is terrible , and utterly unimaginable news for us in Kenya , where there has been so much suffering recently , '' Lone said . He did not know what caused the crash , but said , `` There is absolutely no hint of foul play . It looks like a terrible tragedy . '' Both Kones and Laboso belonged to the Orange Democratic Movement party ( ODM ) , which joined Kibaki 's Party of National Unity ( PNU ) in a coalition government earlier this year under an United Nations-brokered agreement that brought an end to the violence that ripped the nation after Kibaki 's disputed re-election in late December . More than 1,000 people were killed and 350,000 were displaced in the violence , according to the Kenyan Red Cross . Under the agreement , Kibaki retained the presidency while ODM leader Raila Odinga became prime minister . A new cabinet took office in April , with equal representation from both ODM and PNU . The officials ' deaths came a day before parliamentary by-elections in five districts in Kenya .
