Former President Nelson Mandela’s daughter, Makaziwe, is believed to have arrived at the Pretoria Heart hospital, where Madiba is being treated for a recurring lung condition.

Her vehicle has been seen entering the hospital premises.

It’s believed Madiba’s wife, Graca Machel, has been at his side since his admission on Saturday morning.

On Monday, the Presidency said Mandela’s condition was “unchanged” from Saturday and that he was receiving intensive care.

“President Jacob Zuma reiterates his call for South Africa to pray for Madiba and the family during this time,” spokesperson Mac Maharaj said.

All vehicles entering the hospital premises were being checked and searched.

Barricades were erected at the spot where journalists had been camping on Monday, forcing the press to move across the street. Police tape was used to cordon off the area.

This was the third time this year the Nobel Peace Prize laureate had been in hospital. At the end of March and in April this year he spent nine days in hospital receiving treatment for his lung problems.

Earlier in March, he was admitted to a Pretoria hospital for a scheduled check-up and discharged the following day.
