CAPE TOWN - U.S. President Barack Obama has landed in Cape Town after a 36-hour stop in Gauteng that saw him meet with President Jacob Zuma and members of the Mandela family.

Obama and his family are set to visit Robben Island later before the president addresses students at the University of Cape Town (UCT).

Obama has hailed former statesman Nelson Mandela as one of the greatest people in history and his personal hero.

Madiba was admitted to the Mediclinic Heart Hospital for a reoccurring lung infection on 8 June. This is the statesman's fourth hospitalisation since December.

In its last update, the Presidency said the 94-year-old was still critical but improving.

Meanwhile, Obama is set to visit the prison that held Madiba for 18 years.

While Obama has been to Robben Island before as a senator, today he will be accompanied by his wife Michelle and their two daughters.

U.S. officials have been working hard for the past month to secure the historic visit.

Later, Obama will address students at UCT where security is also expected to be extra tight as dozens of anti-American protesters are set to gather.

The protesters are opposed to the American foreign policy and its drone attacks.

The group has promised to be peaceful.
