Namibia's third president Hage Geingob died in the early hours of Sunday while receiving treatment for cancer.
The veteran leader was a strong anti-apartheid activist and lived outside Namibia for decades while South Africa ruled the country. He returned after independence in 1990 to become the former German colony's longest-serving prime minister.
What we know so far
Geingob was being treated at the private Lady Pohamba hospital in the Namibian capital, Windhoek, after his medical team had discovered cancerous cells following a biopsy.
The presidency announced on February 2 that Geingob had returned from the US, where he had received "a two-day novel treatment for cancerous cells."
Geingob's wife, Monica Geingob, and his children were at his side, acting president Nangolo Mbumba said in a statement on social media.
"The Namibian nation has lost a distinguished servant of the people, a liberation struggle icon, the chief architect of our constitution and the pillar of the Namibian house," Mbumba said.
The acting president said the Cabinet would meet swiftly to make the necessary state arrangements, and further announcements would follow.
