Felicien Kabuga, an 87-year-old Rwandan businessman, is currently awaiting trial at the International Criminal Court in The Hague for his part in one of the most gruesome massacres of the 20th century.
Rwanda is a small country in central Africa, but in just 100 days in 1994 members of the Hutu ethnic majority murdered as many as 800,000 people, mostly of the Tutsi minority. On top of that, tens of thousands of other people suffered horrific injuries.
In preparation for the atrocity half-a-million machetes were imported into the country in the previous year, one for every three adult Hutus.
All the charges against Kabuga relate to the genocide and he has been named as one of the main importers of the machetes, the long-bladed weapons which were used to hack their helpless victims to death.
That was in 1994, but today wars and atrocities are taking place in many of the countries across equatorial Africa.
There has been civil war in Somalia since 1990, with 500,000 people killed and more than 1.1 million people displaced as refugees.
Islamist insurgents have been operating in northern Mozambique since 2017. Last year the rebels pledged allegiance to Islamic State and there are reports of massacres and beheadings. Film footage of some of the violence has been incorporated into Isis propaganda films.
In the Democratic Republic of Congo there has been growing violence since the 1990s, with murder, rape, forced disappearances and the use of children as soldiers.
In just three days in December 2018, 900 people were murdered in a tribal conflict at Yumbi, north of Kinshasha.
In Ethiopia there is ongoing ethnic violence between the Oromo, Amhara, Tigrayan and Gedeo peoples and, in some areas, this violence has now reached the level of genocide.
Recently the Barnabas Fund, which monitors persecutions around the world, reported that hundreds of Christians have been murdered this summer by Muslim extremists in the Oromia region.
In Nigeria, since 2009, the Islamist terror group Boko Haram has killed tens of thousands of innocents and displaced 2.3 million people from their homes. Many have fled into neighbouring countries such as Chad, a place with its own long history of atrocities.
A former President of Chad was convicted in 2016 of a litany of war crimes and crimes against humanity.
In the Central African Republic there is continuing violence between the majority community and minority Muslim militias. There is a humanitarian crisis and in some places a state of genocide.
In country after country across the centre of Africa there is a pattern of atrocities on a vast scale.
This is not ancient history from centuries ago; it is happening now and, in each and every case, the lives that are being taken are black lives. The victims are black, the perpetrators are also black, and it is happening on a monumental scale.
Does the situation faced by black victims in central Africa not merit more attention, because that is the place where most black lives are being taken, day after day and year after year and on a scale that is hard to believe?
Yet, some Black Lives Matter activists in Britain seem more interested in vandalising statues of Winston Churchill, demonising Britain and demanding that institutions be renamed, while at the same time mining British history books to identify more grievances.
Some even argue that this current and recent ethnic violence among Africans is the legacy of past European colonialism, but that argument does not stand up to scrutiny.
There were tribal and ethnic wars in Africa long before any Europeans arrived, and in all of these both the perpetrators and the victims were black.
There was also slavery in Africa before any Europeans arrived and there was imperialism in Africa before any Europeans arrived. African Muslims actually invaded Europe as far back as the year 711.
So, why do we hear so little about that history of violence? And why are Black Lives Matter activists seemingly silent about the current wars and tribal genocide in Africa?
Do they not believe that all lives matter and that all black lives matter — even when the perpetrators are also black?
Felicien Kabuga was on the run for decades until his arrest in France, where he is currently in prison.
His forthcoming trial may help to raise awareness of what is happening in Africa, even today.
