Zimbabwean leader warns will 'flush' out opponents

Zimbabwean President Emmerson Mnangagwa on Tuesday warned he would "flush out" political opponents as rights groups reported dozens of activists had been arrested in a crackdown.

Mnangagwa, who took over from longtime ruler Robert Mugabe after a coup in November 2017, said his administration was facing "many hurdles and attacks" including "divisive politics of some opposition elements".

"The bad apples who have attempted to divide our people and to weaken our systems will be flushed out," he warned in a nationwide address. 

"We will overcome attempts at destabilisation of our society by a few rogue Zimbabweans acting in league with foreign detractors."

The Zimbabwe Lawyers for Human Rights said Tuesday it had represented more than 20 people arrested since last week when authorities thwarted anti-government protests that had been scheduled for last Friday.

The protests had been called by opposition politician Jacob Ngarivhume, head of a small party called Transform Zimbabwe, against alleged state corruption and the country's slumping economy.

Police banned the protests and government described them as an "insurrection".

Amnesty International has condemned what it calls the "witch-hunt and repression of peaceful dissent."
