Tunisian President Beji Caid Essebsi is in hospital after suffering a “severe health crisis”, officials say.
They gave no further details. Mr Essebsi – who at 92 is the world’s oldest sitting president – was also treated in hospital last week.
PM Youssef Chahed said Mr Essebsi was receiving all the attention he needed and people should stop spreading “fake news” about his condition.
There had been reports that the president had died.
