Army leaders are at odds with Zimbabwe President Robert Mugabe and his ruling party.
On Tuesday, the ruling ZANU-PF party said the country's army commander "meant to incite insurrection." A day earlier, Gen. Constantino Chiwenga said "the military would not hesitate to step in" to stop what he called a "purging and cleansing process" to remove "members of the party with a liberation background."
The general was talking about a recent shuffle in the party.
Last week, Mugabe fired his vice president. Many saw the move as a way to boost his wife in her political aspirations to succeed the 93-year-old leader.
Vice President Emmerson Mnangagwa has the support of army veterans; he's one of the few remaining members of Zimbabwe's first cabinet after winning a war of independence from white-minority rule. The military has said it would only back a leader who participated in the liberation and has intervened to tamp down outside opposition.
With tensions running so high, questions began to swirl about the likelihood of a coup.
It didn't help that on Tuesday, a handful of tanks and military vehicles were seen near the capital city Harare. News outlets pointed out it was unclear whether or not the troop movement was routine or a show of force.
Correction: A previous version of this story incorrectly said the ZANU-PF denied a coup was taking place in Zimbabwe.
