Zimbabwe’s president Robert Mugabe has been seen arriving at a university graduation ceremony this morning in his first public appearance in two days.

The 93-year-old leader, who has been holding direct talks with the country’s army, is reportedly refusing to step down amid growing calls for his resignation following a military coup on Wednesday.

The army said it would advise the public on the outcome of talks “as soon as possible”.

However, a senior member of Mugabe’s ZANU-PF party told Reuters that Mugabe’s time is limited:

If he becomes stubborn, we will arrange for him to be fired on Sunday. When that is done, it’s impeachment on Tuesday.

One source close to the army leadership told the AFP news agency:

I think he [Mugabe] is trying to buy time.

What’s happened so far?

Almost two weeks ago, Mugabe sacked his vice-president, Emmerson Mnangagwa, accusing him of plotting against the presidency.

While Mugabe wanted his wife Grace to succeed him if he decided to resign, that now seems unlikely.

Throughout the day, soldiers and armoured vehicles encircled parliament and other government buildings.
