Moyo also called on political parties to “discourage” their members from turning to violence.
“To the youth, we call upon you to realise that the future of the country is yours, do not be enticed by the dirty coins of silver, be disciplined and remain committed to the ethos and values of this great nation.”
Al Jazeera spoke to a journalist in Harare, who said the situation in the city was “very tense” with troops on patrol in civilian areas.
“The streets are empty and people haven’t reported to work in fear of what is happening,” said the journalist, who did not want to be named for security reasons.
Nii Akuetteh, an African policy analyst based in Washington, told Al Jazeera that the military would be keen not to portray their actions as a coup in order to avoid attracting opposition.
“However, looking at their actions there is no way to call it another thing. If it is not a coup, the military should be back in their barracks,” he said, adding: “The military is supposed to be defending the country from external enemies.
“We don’t have any news at all suggesting that Zimbabwe has been attacked by external enemies. If there is a criminal operation, it is supposed to be (handled) by the police.
“Now, we should watch if there are divisions in the military, and if and when, Mugabe will make a statement and what he will say.”

There has been a coup d'etat in Zimbabwe by the military. President Robert Mugabe, who has been in power since 1980, is in custody. The military guarantees his safety, including that of his family. pic.twitter.com/CWI831I53E
