South Sudan’s President Salva Kiir has postponed the swearing in ceremony of new legislators.
The 650 members of the Reconstituted National Legislature: The Transitional National Assembly and the Council of States were to take an oath on Friday but will do so on Monday.
The reason for the cancellation was cited as its coinciding with Martyrs' Day - the day the nation's founding father John Garang died in a helicopter crash in 2005.
The day also celebrates other people who died during the struggle for the country's independence.
President Kiir urged the public to remember their loved ones quietly in their homes.
