The twitter handle allegedly being run the provisional government says Emmerson Mnangagwa will address the nation soon as acting president.
The announcement followed another announcement from the same handle that President Robert Mugabe had agreed to step down but will move to South Africa.
It says Movement for Democratic Change leader Morgan Tsvangirai will be appointed interim Prime Minister and head of government.
First Lady Grace Mugabe has agreed to return to Zimbabwe and will be flying from Namibia today.
It is not clear whether this twitter handle is authentic or not as several have sprung up over the past few days.
One handle which went under the title of @ED_ Mnangagwa was very active last week after Mnangagwa was fired as Vice-President but was shut down after the military take over yesterday.
A new handle under @pesmnangagwa has surfaced and feeds into the provisional government one.
