Eighteen properties - mostly houses in Windhoek - remain South African state assets after the new South African government under former President Nelson Mandela handed over 24 properties to Namibia.

The Minister of Works and Transport, Erkki Nghimtina, said in Parliament on Thursday that the properties were handed over to the Namibian Government after Mandela had visited the country in 1994.

He was responding to a question from Congress of Democrats (CoD) Ben Ulenga, who wanted to know which immovable property currently being used by the Namibian government belongs to South Africa.

Nghimtina said his ministry is not aware of any properties belonging to South Africa being occupied by the Namibian government.

He said the Old State House and Suiderhof Military Base were transferred to Namibia in 1995.

The Old State House has been transferred to the Office of the Prime Minister, and the Suiderhof Military Base is used by the Namibia Defence Force.
