Army chief threatened to intervene in politics earlier this week
Zimbabwe's ruling party accused the head of the armed forces of treason, escalating the rupture between Mr Mugabe and the military's top brass.
The events came less than 24 hours after military chief General Constantino Chiwenga threatened to intervene to end a government purge in the ruling party.
The Southern African nation has been on edge since Monday, when armed forces chief Constantino Chiwenga openly threatened to intervene in politics, a week after Mr Mugabe fired vice-president Emerson Mnangagwa, long seen as 93-year-old Mr Mugabe's likely successor.
In the statement, the ruling party said it stood by the "primacy of politics over the gun" and accused General Chiwenga of "treasonable conduct … meant to incite insurrection".
