HARARE, Zimbabwe — Armored personnel carriers have been seen outside the capital of Zimbabwe a day after the Army commander threatened to “step in” to calm political tensions over the president’s firing of his deputy.

The Associated Press saw three APCs with several soldiers in a convoy on a road heading toward an Army barracks just outside Harare.

While it is routine for APCs to move along that route, the timing heightened unease in this southern African country that for the first time is seeing an open rift between the military and 93-year-old President Robert Mugabe. The military has been a key pillar of Mugabe’s power since independence from white minority rule in 1980.

Mugabe last week fired Vice President Emmerson Mnangagwa and accused him of plotting to take power, including through witchcraft. Mnangagwa, who enjoyed the backing of the military and was once seen as a potential successor to Mugabe, fled the country and said he and his family had been threatened. More than 100 senior officials allegedly supporting him have been listed for disciplinary measures by a faction associated with Mugabe’s wife, Grace Mugabe.

The first lady, whose political profile has risen in the past few years, now appears positioned to replace Mnangagwa, leading many in Zimbabwe to suspect that she could succeed her husband as president.

On Monday, Army commander Constantino Chiwenga issued an unprecedented statement saying purges against senior ruling ZANU-PF party officials linked to the 1970s liberation war should end “forthwith.”

“We must remind those behind the current treacherous shenanigans that when it comes to matters of protecting our revolution, the military will not hesitate to step in,” the Army commander said.

Mugabe did not respond to the military statement, and government spokesman Simon Khaya Moyo said only the president could respond. The state-run broadcaster did not report on the statement.

The ruling party’s youth league, aligned to the first lady, on Tuesday criticized the Army commander’s statement, saying youth were “ready to die for Mugabe.”

The Army’s spokesman was not immediately available for comment Tuesday. State broadcaster Zimbabwe Broadcasting Corporation was operating as usual, and the capital remained calm.

“Silence from the Zimbabwean government in these circumstances reinforces impression they are not in control,” Piers Pigou, southern Africa consultant for the International Crisis Group, said on Twitter.

Mugabe in the past has warned military commanders from interfering in ZANU-PF succession politics. “Politics shall always lead the gun, and not the gun politics. Otherwise it will be a coup,” he told supporters in July.

Frustration has been growing in once-prosperous Zimbabwe as the economy collapses under Mugabe, the world’s oldest head of state. The country was shaken last year by the biggest anti-government protests in a decade, and Mugabe’s appointment of a minister for cybersecurity last month was criticized by activists as a crackdown on social media users.
