Zimbabwe latest: Mugabe in crunch talks over his future
Zimbabwe's long-time President Robert Mugabe has been holding direct talks with the army over his future.
Pictures emerged of the 93-year-old meeting the army chief and two envoys from South Africa at his official residence in Harare.
The army put Mr Mugabe under house arrest on Wednesday after moving in to take control.
Opposition leader Morgan Tsvangirai says Mr Mugabe must resign but sources suggest the president is resistant.
The crisis stems from a power struggle in recent months over who might succeed him - his wife Grace Mugabe or former Vice President Emmerson Mnangagwa.
Last week, Mr Mugabe came down in favour of his wife, sacking Mr Mnangagwa and provoking the ire of the army chiefs.

So what's going on in Harare now?
It's very unclear.
Photos in the Zimbabwe Herald showed Mr Mugabe meeting army chief Gen Constantino Chiwenga and the two South African envoys from the Southern African Development Community (Sadc) at State House in Harare.
Alongside them was Father Fidelis Mukonori, a Roman Catholic priest known to Mr Mugabe for years, who has been brought in to mediate.
Sources close to the talks say Mr Mugabe - who has been in control of Zimbabwe since it threw off white minority rule in 1980 - is refusing to stand down voluntarily before next year's planned elections.
"He is refusing to step down. I think he is trying to buy time," one source close to the army leadership told the AFP news agency.
Zanu-PF officials had earlier suggested Mr Mugabe could remain nominally in power until the party congress in December, when Mr Mnangagwa would be formally installed as party and national leader.
What is the view among Zimbabweans?

Many Zimbabweans almost instantly warmed to the military's move to take control of the country, and confine President Mugabe to his official residence.
"The military has done a good thing," says one bookseller. "They will ensure we get a transitional government."
He is firmly convinced that Mr Mugabe's 37-year rule is coming to an end.
There has been a sudden change of tone in the country, and the sense is that many Zimbabweans have been yearning for change.
Any change, it seems, would do.
What do South Africa and the region want?
South Africa is hosting millions of Zimbabweans who fled after the country's economy crashed in 2008. It has a special interest in seeing stability restored.
South African Defence Minister Nosiviwe Maphisa-Nqakula and State Security Minister Bongani Bongo are the envoys meeting Mr Mugabe on behalf of Sadc, which South Africa currently leads.
They will be pushing for a democratic solution. The body, which represents 16 countries, does not support coup-led governments as this would set a dangerous precedent in the largely peaceful region, says the BBC's Pumza Fihlani in Johannesburg.
The head of the African Union (AU), Guinean President Alpha Condé, was clear the AU would "in no case accept" a military seizure of power. He said he was "inviting the army to return to its barracks and return to constitutional order".
And Zimbabwe's opposition?
Mr Tsvangirai, head of the Movement for Democratic Change-Tsvangirai (MDC-T) party and the main opposition leader in Zimbabwe, said on Thursday: "In the interests of the people, Mr Robert Mugabe must resign... immediately."
Mr Tsvangirai, who has been abroad receiving treatment for cancer, also called for a "negotiated all-inclusive transitional mechanism" that would lead to "comprehensive reforms for free and fair elections to be held".
This has been echoed by another Zimbabwean opposition leader, Tendai Biti, who also spoke of the need for a "transitional period".
What's happened to Grace Mugabe?
Early reports suggested Mrs Mugabe had fled to Namibia, but sources now say she is in the family compound along with senior figures from the "Generation-40" group that backs her - cabinet ministers Jonathan Moyo and Saviour Kasukuwere.
On Wednesday, one of her key allies, Zanu-PF youth wing leader Kudzai Chipanga, made a televised apology for criticising the head of the army as a war of words raged prior to the military takeover.
Mr Chipanga is thought to be in army custody but insisted his statement was voluntary.
Local media reports say a number of other senior members of the "Generation-40" group have also been detained.

How did the military takeover come about?
In the early hours of Wednesday, Zimbabwe's military took over the headquarters of national broadcaster ZBC and issued a statement saying they were targeting "criminals" around President Mugabe.
Troops and armoured vehicles encircled parliament and other key buildings throughout the day.
On Monday, Gen Chiwenga had warned the army would intervene to end what he called the "purging" of Zanu-PF members "with a liberation background", referring to the country's struggle for independence.
Mr Mnangagwa is one such veteran of the 1970s war which led to independence.
