"It is with deep sorrow and shock that we announce the sudden passing on of Interior CS Retired General Joseph Nkaissery," said a statement from Kenya's State House.

The government said on Saturday that Interior Minister died at a hospital in the capital, Nairobi.

Nkaissery, 68, a retired army officer, had held the position of cabinet secretary for interior and coordination of national government since late 2014.

The statement said Nkaissery died "at Karen Hospital in Nairobi a few hours after being admitted for a check-up" without providing further details on the cause of death.

Nkaissery was a Member of Parliament from 2002 until 2014 when President Uhuru Kenyatta named him interior minister to replace Joseph Ole Lenku who was dismissed following a spike in insecurity and terror attacks in Kenya.
