On Friday former first lady Graca Machel thanked all those who had contributed one way or the other to make the opening of the Nelson Mandela Children’s Hospital in Johannesburg a reality‚ saying it was a monument to Mandela’s love and care for children.

She then singled out the efforts of Health Minister Aaron Motsoaledi‚ sneaking in what some are saying is  to be considered  a jab at the government.

“The government of South Africa‚ and in this case we will say minister Motsoaledi‚ thank you so much. First‚ for having understood the nature of this hospital. There were very many people who fought the idea of the hospital … but the minister was very very clear and from the onset had been a champion of the children’s hospital.

“We hope that you will continue to mobilise your colleagues in that government to continue to support this initiative.”

Twitter users were quick to react‚ accusing Machel of throwing shade.
