Zimbabwe's former President Robert Mugabe, 94, is unwell, the ruling party has tweeted:
“We have received news that our former 1st Secretary and President R.G Mugabe is not feeling well. Get well soon Gushungo. His Excellency the President of the Republic of Zimbabwe @edmnangagwa will ensure you get the best medical care you deserve.”
The tweet came hours after President Emmerson Mnangagwa was sworn in as Zimbabwe's second elected president at a huge rally in the capital, Harare, on Sunday.
Mr Mugabe and his wife, Grace, were not at the ceremony.
Mr Mugabe caused a stir by backing opposition candidate Nelson Chamisa in the heavily disputed elections held on 31 July.
With the help of the military, Mr Mnangagwa ousted Mr Mugabe as president in November, ending his 37-year rule.
