The president of Zimbabwe, Emmerson Mnangagwa, appointed a new army leader on Monday before the planned demonstrations, called by a group of war veterans who wish to force the president to resign.
The former major general, Emmanuel Matutu, takes over with an immediate effect.
President Mnangagwa faced calls from his former supporters to resign, citing poor management and corruption.
Earlier this week, Mnangagwa suddenly withdrawn his army chief, Lieutenant-General Anselem Sanyatwe, appointing him Minister of Sports, Arts and Culture.
Due to its ruthless reputation, Emmerson Mnangagwa Go through the nickname “Le Crocodile”.
He became president in 2017 following a coup d’etat against the long -standing leader Robert Mugabe, and is currently serving his second and last mandate, which expires in 2028.
The problems began to brew on in the gatherings of the Zanu-PF ruling party last year after pointing that Mnangagwa wanted to remain in office.
Despite recent insurance from Mnangagwa, which he intended to resign in three years, many remain unconvinced.
The criticism of his leadership of his party and the accusations that he intends to cling to power spoke of memories of the advantage to the coup who overthrew Mugabe.
Although it is not clear how much public support the veterans have for their planned demonstrations, the Minister of Security warned the Zimbabweans not to participate in the demonstrations.
Police announced a four -day ban around the capital on the transport of weapons or any instrument that can be used to cause violence.
