This came as tensions were mounting in Zimbabwe after Mugabe last week expressed support for the National Patriotic Front led by former cabinet minister and ally Ambrose Mutinhiri.
Mutinhiri, last week, quit Zanu PF over what he called "the unconstitutionality of the military coup that illegally imposed Emmerson Mnangagwa as President of Zimbabwe during 'Operation Restore Legacy".
Speaking at a Zanu PF youth meeting, the party's youth league secretary, Pupurai Togarepi ridiculed Mugabe, saying the former President was behaving like he was possessed. "We are coming", he said.
Former Zimbabwean President Robert Mugabe reportedly flew to South Africa on Wednesday for the first time since stepping down from power in November past year. He must withdraw his behaviour and be responsible.
"Currently, we see and hear various speculations and I have no doubt that very soon the facts and reality will be known. It is the Youth League's responsibility to defend the Revolutionary Party", Togarepi said.

Willian has had a hand in 16 goals in his last 17 starts for Chelsea in all competitions (11 goals, 5 assists). Nothing but a win would suffice on Saturday if they were to remain in contention for a place in the top four.
"We will not be happy if he takes what he is getting from the government to destroy our revolution, destroy your government, destroy the future of the youth". "It is an issue we are examining".
The NPF said it was formed by ZANU-PF members and Zimbabweans outraged by the "unconstitutional" and "humiliating" manner in which President Mugabe was "criminally" ousted from leadership.
In response to that, President Mnangagwa, who has on several occasions hailed Cde Mugabe as his father, mentor and the country's liberator, said if the reports are true, they are not amusing.
The veteran leader was revered in the ruling party, but yesterday, his name was met with derision, with slogan pasi na (down with) Robert Mugabe being chanted at the meeting.
This week, the NPF wrote to the Zimbabwe Electoral Commission informing it that the party would be taking part in the general elections and so should also be included in programmes that involve political parties and the upcoming elections.
