President Uhuru Kenyatta has declared three days of mourning following the death of former South African President Nelson Mandela.

"The President also ordered flags to be flown at half-mast for three days in honour of the legendary African leader starting tomorrow, Saturday 7th December 2013," read a statement from the PSCU Friday.

The anti-apartheid hero died late Thursday after a long battle against lung infection. Leaders, celebrities and citizens from all walks of life have joined hands in sending messages of condolences to the fallen hero who has been described as a father of the South African nation.

A period of mourning will precede the 95-year-old's burial worldwide, with South Africans expected to mark his death at official memorial services across the country, including at Johannesburg's Soccer City, the host stadium of the 2010 World Cup final where Mandela made his last major public appearance.
