They need to stop saying Mandela is doing well. Look at him, a Twitter user wrote.
Another user wrote: Mandela is not in a good shape, the government have the nerve to lie straight to our faces.
The SABC broadcast exclusive footage of the ailing Mandela, showing him sitting impassively with a blanket over his legs.
He was flanked by Zuma, ANC deputy president Cyril Ramaphosa, party chairperson Baleka Mbete and his medical team.
The Nobel Peace Prize laureate looked blankly at the camera while everyone around him stood chatting and laughing.
A frail Mandela was seen closing his eyes as someone's camera flash light clearly affected his eyes.
Mandela is known to have sensitive eyes after years of working in a limestone quarry when he was imprisoned on Robben Island.
The African National Congress' top leaders visited Mandela at his Houghton home in Johannesburg earlier on Monday.
The report said he was in good spirit.
President Jacob Zuma told the state broadcaster that Mandela was "up and about" but the former president showed little emotion while being filmed with Zuma seated next to him.
"We had some conversation with him, shook hands, he was smiling," Zuma told the SABC.
"He's really up and about, [and] stabilised. We are very happy, we think he is fine."
A Twitter user wrote: Mandela can't even turn his heard but Zuma says he's in good shape.
Poor Nelson Mandela. Let him be. No elderly person deserves that, said another user.
After everything the man has done for us this is how we treat him. Like an animal at the zoo. Shame on us. #mandela.
Other users said: After months of attacking media for "invading" Mandela's privacy, ANC today released an invasive video of a clearly ailing and grim Mandela.
SABC claims Mandela looks "relaxed" and "in good spirits" but the new video contradicts that claim.
The affair was described as "undignified".
I didn't like seeing that exclusive footage of Mandela at all. There was something undignified about the whole affair.
I'd show no emotions if zuma sat with me. I mean, zuma is destroying everything Mandela fought for! Madiba must be a very sad man
No one should ever have their home invaded by politicians. Ever. #Mandela
We can't repeat this enough, he has served us as humanity nowits time for Pres. Mandela to rest. Leave him ALONE PLEASE, said another.
Mandela was discharged from hospital earlier this month after spending nine days receiving treatment for recurring lung problems. He has had lung ailments before.

In December last year, Mandela underwent an operation to remove gallstones and treat the recurring lung infection.
He was discharged after an 18-day stay and placed under home-based high care at his Houghton home.
In January, the presidency said Mandela had made a full recovery from the surgery and continued to improve.
In February last year he was admitted to hospital for a stomach ailment.
