Emergency workers in South Africa say a foetus has been found in a skip bin in a business area of the capital, Pretoria.

Netcare 911 says its paramedics were called to the scene by some people working in the area. They found “the female foetus” wrapped in a number of plastic bags.

"We suspect that the foetus was not full term. She had no chance of life," local media quoted Netcare 911 spokesman Nick Dollman as saying.

"Upon assessment, paramedics found that the female foetus was still attached to her placenta. Tragically, there was nothing that paramedics could do to help the lifeless victim," he added.

The foetus was handed over to the police who are expected to carry out an investigation.

Previous cases involving the dumping of newborn babies in garbage bins have led to charges of murder or manslaughter, referred to as culpable homicide in South Africa.

The dumping of a foetus is a trickier case and there are not enough details at this point to know what will happen next.

Two children with albinism were killed in separate attacks in Mozambique at the weekend, police have said.

Unidentified men used a hoe to beat a six-year-old boy to death in central Mozambique's Mulumbo district, said police commander Miguel Caetano.

He added that the child's brother-in-law, who is currently on the run, is wanted in connection with the killing.

In a second incident, a 13-year-old girl was brutally killed with "blunt instruments" in the Manhewe area in northern Mozambique.

A police spokesperson said the "unidentified criminals killed the child, threatened to kill the child's father, attacked his wife and abducted a three-year-old brother of the dead girl".

Police have not yet found the boy.

People with albinism are hunted down in parts of Africa because of the belief that potions made from their body parts can bring good luck and wealth.

A close friend of South African anti-apartheid activist Ahmed Timol has disputed the former regime's claim that he took his life by jumping from the 10th floor of the police headquarters in 1971.

“I would have no doubt in my mind that he would never have discussed the matter of suicide, having known Timol for as long as I did," said Essop Pahad.

He was testifying at the re-opened inquest into the death of Mr Timol, a school teacher whose death in detention, at the age of 30, caused global outrage.

This is the first time since the racist system of apartheid ended in 1994 that an inquest into the death of an activist has re-opened.

Mr Timol's relatives put intense pressure on the democratic state to re-open the inquest after the Truth and Reconciliation Commission - formed after apartheid ended - failed to investigate his death.

The family is pushing for the findings of the original inquest to be overturned, saying it was a cover-up.

It ruled that the police officers who had interrogated Mr Timol - who was a member of the outlawed South African Communist Party (SACP) - were not responsible for his death, and he had taken his own life.

His family strongly disputes this. It wants the new inquest to rule that Mr Timol was brutally tortured, and was flung out of the window by the police.

Mr Timol was based in the UK before he returned to South Africa in 1970.

Mr Pahad - a former senior member of the SACP and the governing African National Congress (ANC) - told the inquest that had shared a flat with Mr Timol in London.

Judge Billy Mothle asked him whether before 1971 he had heard of any SACP member taking his own life.

“No, I’m not aware of anybody,” replied Mr Pahad, who served in South Africa's government after the end of minority rule.

A policeman, who was the last person to see Mr Timol, has been subpoenaed to testify at the inquest.

On Monday, apartheid-era policeman Paul Erasmus told the inquest that detainees were tortured.

“I witnessed the first ever torture on the 10th floor; a man’s testicles were being crushed,” he said, the City Press newspaper reported., external

The former regime had alleged that the SACP instructed its members to kill themselves, rather than disclose details of their activities to the police.

The French President Emmanuel Macron is hosting face-to-face talks between two rival Libyan leaders in the latest bid to try to bring stability to the country.

Fayez al-Sarraj, the head of the UN-backed government, and Khalifa Haftar, who leads the so-called Libyan National Army in eastern Libya, are yet to reach a compromise on sharing power.

Earlier we reported that parents at a school in South Africa blocked the entrance in protest to a black principal being appointed, insisting that they have a "coloured" (mixed race) principal.

The school has reopened after yesterday’s protests and it is operating normally again.

The Department of Education spoke to protesters and said the majority were community members who caught wind of the appointment rather than parents.

Oupa Bodipe, the department of education spokesperson, said that the calls for the black principals to be removed are based on community members wanting to see someone who looks like them working in these institutions.

But Mr Bodipe said that, although Klipspruit is a historically "coloured" area, the majority of the school is comprised of black African students and it’s very much a racially mixed school.

He said that the department has explained that the appointment of the principal was lawful, and that there are no grounds to reverse it.

Nigeria's ailing President Muhammadu Buhari has written to his Guinean counterpart Alpha Conde to thank him for the nationwide prayers he had organised for his recovery, his spokesman Femi Adesina has said

Mr Buhari, 74, has been in the UK for almost 80 days, receiving treatment for an unspecified illness.

In his letter, Mr Buhari assured Mr Conde - the current chairman of the African Union - that he was making "good progress", and would return to Nigeria to resume his presidential duties as soon as his doctors gave him the go-ahead, Mr Adesina said.

In an earlier letter, Mr Buhari had also accepted his nomination as leader of the "2018 AU Theme on the Fight Against Corruption", Mr Adesina added.

"I wish to express my readiness to accept this new important role and to reiterate my commitment to contribute towards our collective efforts to strengthen good governance and development on the continent," Mr Buhari said in the letter.

He was nominated for the role at the summit of AU leaders in Ethiopia on 4 July.

Mr Buhari's long absence has caused some anxiety in Nigeria, and has led to speculation that his rivals were plotting to succeed him.

Researchers in the United States say a trial in which American teenagers used a vaginal ring to prevent HIV infection has proved successful.

A further such study will now be run with teenagers in Africa.

The girls used a flexible plastic ring, embedded with anti-retroviral drugs, which was changed every month over a six-month period.

It's part of a drive to develop a device which women can use to protect themselves from HIV infection, so they don't have to rely on men to wear condoms.

Reporting the development at a conference about HIV science in Paris, the researchers said they were encouraged that the girls used the ring and said they liked it.

Women and girls aged 15-24 account for a fifth of all new HIV infections globally.

Nearly 1,000 are infected every day in sub-Saharan Africa.
