It’s 70 years since General Alfredo Stroessner seized power in Paraguay in a military coup.

Stroessner remained in power for almost 35 years, before being toppled in 1989.

More than 450 people were murdered under Stroessner's rule, with the fate of thousands more unknown. They are remembered as 'the disappeared' of Paraguay.

One man has dedicated his life to finding the victims of Stroessner's dictatorship, including the remains of his own father.

Rogelio Goiburu shares his story with Matt Pintus.

On 13 December 1990, the anti-apartheid politician Oliver Tambo returned to South Africa after 30 years in exile.

As the president of the banned African National Congress (ANC), he had lived in Zambia building the liberation movement while other key ANC members including Nelson Mandela and Walter Sisulu were political prisoners.

By lobbying around the world and attracting talented South African exiles such as Thabo Mbeki, he built the organisation into a legitimate contender for government.

When President FW de Klerk unbanned the ANC, Oliver or OR Tambo was finally able to return home where he was greeted by a crowd of thousands at the airport.

Oliver Tambo’s son, Dali Tambo, recalls to Josephine McDermott how his father and other ANC exiles danced in the aisle of the plane as they crossed into South African airspace.

Brenda Fassie was one of South Africa's biggest pop stars in the late 1980s. The singer’s career nosedived in 1990, but her comeback saw her dubbed the 'Madonna of the townships' by Time magazine.

Yvonne Chaka Chaka, born a year after Brenda, was perhaps the only South African pop star who could rival her popularity.

Twenty years ago, in 2004, Brenda died

In August 2002, the remains of an indigenous South African woman called Sarah Baartman were returned to South Africa after almost 200 years away. Sarah died in Paris in 1815 after being forced to perform in European 'freak shows' where people considered to be biological rarities were paraded for entertainment. She had been subjected to racist and degrading treatment and her remains were exhibited at a French museum until 1976.

When Nelson Mandela became the president of South Africa in 1994, he requested that Sarah's remains be returned to her homeland. However, by 1998 that had not happened. Poet Diana Ferrus decided to write about Sarah’s limbo. Her poem became so popular that it was noticed by politicians in France. Diana shares her memories of that time with Matt Pintus.

When South African schoolchildren marched in protest against having to study Afrikaans in 1976, they were gunned down by the police.

The killings sparked a cycle of protests across the country against the racist apartheid regime.

In 2010, march organiser Bongi Mkhabela told Alan Johnston about her memories of the Soweto uprising.

On 18 March 1992, white South Africans overwhelmingly backed a mandate for political reforms to end apartheid and create a power-sharing multi-racial government.

It was a high-stakes referendum coming on the back of three by-elections where the ruling National Party had lost to the right wing Conservative party.

In a speech after the polling victory, President FW de Klerk said: “Today we have closed the book on apartheid”. His communications adviser, David Steward speaks to Josephine McDermott.

Major Charity Adams was the first African-American woman to lead a World War Two battalion. It was known as the Six-Triple-Eight (6888).

The 6888 was a majority African-American women’s unit, the women sorted through mountains of post across Europe, using the motto: 'No Mail, Low Morale'.

Charity went on to become lieutenant colonel, the highest possible rank for women in her unit. She died in 2002.

Her son, Stanley Earley, speaks to Marverine Cole.

This was a Soundtruism production for the BBC World Service.

On 18 April 2014, an avalanche on Mount Everest killed 16 men, who were carrying supplies for commercial expeditions to higher camps.

The sherpas were on the Khumbu Icefall, just above Base Camp in Nepal, when the avalanche happened.

It resulted in the climbing season being cancelled and sherpas demanding better working conditions on the mountain.

Lakpa Rita Sherpa helped dig bodies of his dead colleagues out of the ice, before transporting them home to their families.

He speaks to Laura Jones.

The 2014 Ebola outbreak devastated West Africa, killing more than 11,000 people over a two year period. One country that suffered was Sierra Leone.

The disease started in Guinea, but quickly spread to neighbouring countries.

Before May 2014, there had never been an outbreak of Ebola in Sierra Leone. By autumn that year, burial teams were struggling to keep up with the number of corpses that needed burying.

When the train service between India and Bangladesh was suspended in 1965, following war between Pakistan and India, it lay dormant for 43 years.

But in a day of celebration in 2008, the Maitree (or Friendship) Express rumbled into life and connected the two countries once more.

In 2020, Farhana Haider spoke to Dr Azad Chowdhury who was on the inaugural train journey.

A group of men known as the ‘Cairo 52’ were arrested in Egypt in May 2001. They were on board the Queen Boat, a floating gay nightclub on the River Nile.

Omer, not his real name, was arrested and imprisoned for habitual debauchery.

There is no explicit law against homosexuality in Egypt and Omer was released early following the orders of US president at the time, George W Bush.

Omer speaks to Dan Hardoon about the arrest and its aftermath – in graphic detail.

This programme has been updated with the correct trial date.
