- Analysts had warned that the sacking would spark repercussions beyond Mugabe's control.
- Zimbabwe goes to elections next year to vote for a president and lawmakers.
- ZANU-PF is due to hold a congress next month, when 52-year-old Grace, a hugely divisive figure, could be appointed as one of the country's two vice presidents.
Zimbabwe's army chief on Monday demanded a "stop" to the purge in the ruling ZANU-PF party after the sacking of vice president Emmerson Mnangagwa, and warned the military could intervene.
"The current purging which is clearly targeting members of the party with a liberation background must stop forthwith," General Constantino Chiwenga told a media conference attended by about 90 senior army officers at army HQ.
In an unprecedented warning, he said in a statement: "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."
Mnangagwa was dismissed and humiliated a week earlier after clashing with veteran President Robert Mugabe's wife Grace, who is now in prime position to succeed her 93-year-old husband.
Analysts had warned that the sacking would spark repercussions beyond Mugabe's control.
Mnangagwa's main rivals within the ruling ZANU-PF- party are the younger "Generation 40" or "G40" group, who enjoy Grace's support.
But the 75-year-old former vice president has powerful military connections, having served as defence and state security minister.
Soon after his dismissal Mnangagwa quickly fled into exile, vowing to return and launched a direct challenge to Mugabe by calling for members of the ruling party to desert the president.
Mnangagwa — whose nickname is the "Crocodile" — defiantly told Mugabe that the party was "not personal property for you and your wife to do as you please".
Mugabe then reacted by expelling his long time confidante and former liberation war guerrilla, from the party.
ZANU-PF is due to hold a congress next month, when 52-year-old Grace, a hugely divisive figure, could be appointed as one of the country's two vice presidents.
The move could pave the way for her to get the top job after Mugabe.
