A prominent Roman Catholic archbishop in Zimbabwe has called for mass street protests to force President Robert Mugabe from power.
Archbishop Ncube said starvation stalked Zimbabwe
The Archbishop of Bulawayo, Pius Ncube, told a news conference in Harare that he was willing to stand in front of "blazing guns" if necessary.
Scores of opposition activists have been arrested since police broke up a banned rally on 11 March in Harare.
There is increasing discontent over the country's deepening economic crisis.
Archbishop Ncube said that if Zimbabweans took to the streets in their thousands to demand that President Mugabe step down, the security forces would be powerless to stop them.
"I am ready to stand in front," he said. "We must be ready to stand, even in front of blazing guns."
The archbishop blamed years of economic and political turmoil in Zimbabwe on a land redistribution programme launched in 2000 that has turned white-owned commercial farms over to blacks.
"Starvation stalks our land and government does nothing to correct our situation," he said.
"People are angry now and should stand up, fill the streets and demand that this man steps down now."
The archbishop has been a long-standing critic of Mr Mugabe and his ruling Zanu-PF party. Two years ago he made a similar appeal in the run-up to elections.

The news conference was organised by one of the groups behind the 11 March rally that was broken up by police.
