A televised rape trial in South Africa has prompted a furious public backlash after a witness - who says she was raped by her pastor from the age of 14.

She was subjected to a lengthy and, at times, aggressively intimate cross-examination by the lawyer representing a 60-year-old Nigerian televangelist, Timothy Omotoso, who denies the allegation.

Over the weekend, Mr Omotoso's church, in the coastal city of Port Elizabeth, was forced to shut its door after angry crowds besieged the building, while a Sunday newspaper reported that the woman who gave evidence against him - Cheryl Zondi, now a 22-year-old student - had received death threats ahead of the trial.

The trial - the first prominent rape case to be broadcast live in a country where more than 100 rapes are reported to the police each day - has attracted huge interest, and raised difficult questions about victims' rights, impartiality and whether justice is best served by having television cameras in courtrooms.

Anti-apartheid icon Nelson Mandela's granddaughter, Ndileka Mandela - who said in 2017 that she had been raped by a former boyfriend - is one of many South African women who have voiced support for Ms Zondi, linking her experience to the global #MeToo movement.

Ms Mandela argued that the student's treatment during three days in the witness box helped explain why so many rape victims stay silent in a nation with notoriously high levels of sexual violence.

Miracles and prophecies

"I really feel pain for this young woman and I am so proud to see how courageous she's been on the witness stand," Ms Mandela told South Africa's Sunday Times newspaper.

Mr Omotoso and two female co-accused, from the Jesus Dominion International church, based in South Africa's Eastern Cape, are facing 97 charges, ranging from sexual assault to rape and human trafficking.

They deny all the charges. The church - one of a growing number of evangelical ministries in the country, promising miracles and prophecies for its followers - is known for its videos of uniformed young women singers, some of whom have appeared on the Idols SA television contest.

Since it began last week, the nation seems to have stopped in its tracks to follow the trial, and social media erupted in support and sympathy for Ms Zondi.

She was the first prosecution witness and told the court, with great composure, that Mr Omotoso - quoting the psalms and threatening God's anger if she did not comply - had allegedly repeatedly raped her a year after she had joined his church as a child.

But public sympathy soon turned to fury when Mr Omotoso's lawyer, Peter Daubermann, sought to challenge her account.

Shouts in the courtroom

"You're a good actress," he said."I put it to you that you are lying about what happened to you.

You were prepared to let him rape you? You basically consented?" he asked, referring to later alleged incidents when Ms Zondi was an adult.

South Africa's justice system is deliberately confrontational, and lawyers are expected to challenge witnesses robustly - perhaps the most famous instance being prosecutor Gerrie Nel's explosive quarrels with disgraced Olympic and Paralympic star Oscar Pistorius during his murder trial.

But in this case, according to the opinion of some experts and ordinary South Africans, Mr Daubermann appeared to cross a line.

"How many centimetres? Do you know?" he asked Ms Zondi, after she had described how the pastor had allegedly partially penetrated her, at the age of 14.

There were cries and shouts in the courtroom."How would she know that?" Judge Mandela Makaula interrupted, visibly angry.

"She could have felt it," suggested Mr Daubermann. "And measured it at the same time? No. I will not allow that question," declared the judge, who went on to thank Ms Zondi for her testimony and to wish her good luck in the university exams she had interrupted in order to attend the trial.

"This is not about you. This is about justice," he told her."Cheryl has set a precedent and we can only pray other victims will be encouraged by this.

We salute her," a local spokesman for the National Prosecuting Authority told journalists.

But Mr Omotoso's defence team has since hit back, accusing the judge of showing bias and asking him to recuse himself from the trial.

"You aligned yourself with her cause. You have already accepted her version," Mr Daubermann told Judge Makaula, arguing that the trial should start again from scratch, and bitterly condemning the media coverage of the case and the social-media frenzy it has triggered.

"I've been vilified in the media for my cross-examination. I've been accused of adopting questionable methods of examination.

That is blatantly false. I have to test the veracity of the evidence. I can't allow sensibilities to get in the way of my duty," said the lawyer after he had been followed and harangued on the street outside the courthouse by an angry crowd.

Judge Makaula refused to recuse himself, saying: "The application has no merit."

Trials on TV

The Pistorius trial was the first to be broadcast live and in full in South Africa.

Since then, the courts have allowed television cameras into a succession of high-profile trials, but while supporters argue that it is important for the population of a young democracy to see the workings of its legal system, critics argue that the presence of cameras inevitably distorts the process and brings unfair pressure on those involved - in the Omotoso trial, for instance, potentially inflaming xenophobic attitudes towards Nigerians.

Ms Zondi, who has since thanked the public for their support, could have chosen - like some witnesses in the Pistorius trial - to give her evidence without the cameras rolling, but declined to do so.

Many more witnesses are now expected to testify against the televangelist, who was dramatically arrested at an airport last year as he sought to leave the country.

He maintains his innocence and continues to enjoy the support of many members of his predominantly female congregation.

In court, his wife has been criticised by the judge for appearing to laugh and comment on Ms Zondi's evidence, while Mr Omotoso himself has appeared relaxed, often smiling, and sporting an array of brightly coloured suits as South Africans wait to hear his version of events.
