HARARE, Zimbabwe (AP) — The Latest on Zimbabwe's political turmoil (all times local):

6:05 a.m.

The head of the African Union Commission is backing efforts by the Southern African Development Community to resolve the political crisis in Zimbabwe.

Moussa Faki Mahamat tells The Associated Press that the AU is working with the regional group. He says he believes a solution will be found that's within "constitutional legality."

The AU leader isn't saying explicitly whether what happened in Zimbabwe was a coup. He says through a translator that there are "divergent views" within Zimbabwe's ruling party.

But he says the AU condemns all unconstitutional changes in government. He says the union rejects any coups, rebellions or mercenary actions to overthrow a democratically elected government.

Cabinet ministers from four countries in the 15-nation SADC have called for an emergency summit to discuss the turmoil in Zimbabwe. It is widely seen as essential to giving Zimbabwean President Robert Mugabe a dignified exit from power after the military stepped in this week.

A newly created Twitter account that claimed to be Zimbabwe's recently sacked vice president — and its incoming leader — has been suspended.

The account @presmnangagwa claimed to represent Emmerson Mnangagwa, whose firing as vice president last week led the military to move in and put President Robert Mugabe under house arrest.

The Twitter account issued a stream of "updates" on the crisis but was quickly questioned by skeptical Zimbabweans, who are no strangers to rumor and speculation.

Links to the account Thursday night lead to a page saying "account suspended." There was no specific explanation for the move, though Twitter says common reasons include spam or abusive behavior.

He also says he hasn't been approached to be part of any transitional mechanism but "if we are approached to negotiate such a process we will participate."

Tsvangirai shared power with Mugabe between 2009 and 2013 before losing disputed elections. He has been receiving treatment for cancer.

An analyst says he believes negotiations in Zimbabwe "have pretty much reached an end point" to get President Robert Mugabe to step aside.

Knox Chitiyo, associate fellow with the Africa program at Chatham House, cautions that speculation remains high but it appears that the Catholic church is involved in the talks with the military and Mugabe.

He says the aim is a peaceful, managed transition. "What is clear, it is now a matter of hours or days before he steps down." Witnesses have confirmed the movement of Mugabe's motorcade in the capital.

Chitiyo says the military has wanted a dignified exit for Mugabe, who has ruled since independence from white minority rule in 1980.
