Zimbabwe's protest pastor responds to political crisis
Zimbabwe's protest pastor, Evan Mawarire, has called the latest developments in his country "unprecedented".
Mawarire went live on Facebook, calling on his fellow Zimbabweans to keep safe.
The "This Flag" social movement leader says this is a situation they didn't see coming.
Military vehicles blocked roads outside the Zimbabwean parliament on Wednesday.
It comes after army generals denied staging a coup but used state TV to vow to target "criminals" close to President Robert Mugabe, AFP reports.

Jacaranda FM News' Zimbabwe correspondent, Zenzele Ndebele, says from what's happening on the ground, it looks like the military is definitely in charge.
Ndebele says reports are emerging of a number of arrests.
Meanwhile, President Jacob Zuma, on behalf of SADC, has issued a statement about the unfolding political situation in Zimbabwe.
In his statement, Zuma calls for calm and restraint.
He says he hopes that the developments in Zimbabwe would not lead to unconstitutional changes of government "as that would be contrary to both SADC and African Union positions".
"The President has urged the Government of the Republic of Zimbabwe and the Zimbabwe Defence Force to resolve the political impasse amicably and has urged the Zimbabwean Defence Force to ensure that the maintenance of peace and security in the country is not compromised," the statement says.
