At least 33 people have been killed and several others injured in central Kenya after a bus veered off a bridge and plunged into a river.

The authorities say that 10 people survived the Sunday night accident.

The vehicle was travelling from the town of Meru to the coastal city of Mombasa when the accident happened.

Police say preliminary investigations suggest the brakes may have failed.

A search and rescue operation is under way and the death toll is expected to rise.

Images from the scene showed the mangled wreckage of the bus with the roof completely ripped off and personal belongings strewn all over.

The bus is said to have veered off the bridge and plunged some 40m below into the Nithi River.

The incident is the latest in a series of deadly road accidents in Kenya.

A video has emerged in Nigeria which appears to show an armed group with some of the hostages that were seized from a train in March.

In the video - which has not been verified by the BBC - the gunmen can be seen flogging the hostages who are lying on the ground.

Most of them are men. Some women - who were shielding their children from witnessing the beatings - can be heard asking the international community to help secure their release.

Eleven hostages were freed last month and at least 40 are believed to be still in captivity.

The Nigerian government says it is against the paying of ransoms but correspondents say criminal gangs have collected huge sums of money in recent years from the frequent cases of kidnapping.

A court in Egypt has called for a legal amendment to allow live broadcast of the execution of the killer of a female student.

Egyptians were horrified after video footage went viral last month purportedly showing Mohammed Adel stabbing to death Nayera Ashraf, who rejected his advances, outside her university.

In a letter to parliament, the court that sentenced the 22-year-old to death said the broadcast of even a part of the proceedings could achieve the goal of deterrence.

Egypt does not broadcast executions, which are always carried out by hanging inside prisons.

A 2015 United Nations survey said nearly eight million Egyptian women were victims of violence.

Nigeria's Tobi Amusan has won gold in the women's 100m hurdles at the World Athletics Championships in the United States.

The 25-year-old broke the world record in the semi-finals with a time of 12.12 seconds. Her time beats the 12.20 seconds set by American Kendra Harrison, who finished second behind Amusan, in 2016.

Amusan went on to win gold in the final, two hours later.

She ran even faster in the final (12.06s), but due to a strong tail wind this will not be registered as a record.

Tears of joy flowed down her face as the Nigerian anthem sounded in the Hayward Field stadium, Eugene, Oregon, for surely the greatest and proudest night in these championships for Nigeria.

A BBC journalist tweeted some of the moments after her win:

What a night it was for Nigeria as they waited the very last day to put themselves on the medals board.

It could have been two golds on Sunday night for the country as long jumper Ese Brume led the field for a while with a 7.02m jump, until German (with Tanzanian roots) Malaika Mihambo bettered her on her fourth attempt (7.09m) and even went further on her last attempts (7.12m).

Brume finished second.

Kenyan police in the capital Nairobi have raided offices believed to be linked to the country's deputy president, William Ruto, who is one of the main candidates in next month's elections.

A police official said detectives had seized two computers and two servers.

An official at the deputy president's campaign secretariat told the BBC they would not want to be drawn to what he described as "mere side shows and distractions".

The raid comes amid tension between the country's security forces and the country's Independent Electoral and Boundaries Commission (IEBC).

Over the weekend the head of the commission strongly criticised a decision to detain three foreign nationals who had been contracted to work on the country's electronic voting system.

The police dismissed allegations by the IEBC, saying there was no evidence showing that the electoral body had contracted the trio or that they were employees of the firm contracted by the commission.

The presidential race is seen as a close contest between Mr Ruto and a former prime minister, Raila Odinga.

On 11th February 1990 anti-apartheid leader Nelson Mandela walked free after spending 27 years in a South African jail. It was a day that millions of black South Africans had been waiting for and marked the beginning of the end of white rule. Fellow activist Valli Moosa remembers that day, and the hasty preparations to make it possible and tells Louise Hidalgo how things almost didn't go to plan.

A flightless bird, the dodo became extinct just decades after being discovered on the uninhabited island of Mauritius by European sailors. Because dodos couldn't fly they, and their eggs, were eaten by explorers and the cats and rats that came with them on board their ships. By the late 1600s there were none left. Simon Watts charts the demise and subsequent popularisation of the dodo.

The Harkis were Algerian Muslims who volunteered to fight with France in Algeria's war of independence. When the conflict came to an end in 1962 and France was forced to abandon its former colony, thousands of its Harki allies were left to face persecution and brutal repression. Serge Carel was an Algerian Harki who joined the French army when he was just 18 years old. When the independence war ended, he was imprisoned and tortured by the country's new rulers. He's been telling Mike Lanchin about his ordeal.

It is feared than in a few months’ time Cape Town could run out of water. The city is planning for so-called Day Zero when the supply is switched off and people will have to collect water rations. Cape Town is an extreme example of what is now a global phenomenon of water scarcity. We investigate how the city got so close to the brink, and whether there’s anything that other cities around the world can do to avoid a similar fate.

Episode three explores how Barack Obama set out to end George Bush's wars in the Middle East and reset relations with the rest of the world. In Cairo he speaks to the Arab world, calling democracy a human right. Two years later when protest erupts in Tahrir Square, the president is torn between secretary of state Hillary Clinton and defense secretary Robert Gates, who believe Egypt's President Hosni Mubarak provides regional stability, and his young advisors, who are in tune with the promise of the Arab Spring. Before long, a similar test arises in Libya, Hillary Clinton changes her position to back military intervention and Obama agrees to join allies in airstrikes against Colonel Gaddafi. In Syria, when shocking evidence shows the use of chemical weapons, Obama decides to bomb. But when the British Parliament votes against intervention, he decides he needs the backing of a reluctant Congress. Foreign secretary William Hague explains why the British parliament voted against intervention in 2013 and President Obama explains why he then decided to seek the backing of Congress.

This episode also explores how Obama scored a big win when he negotiated a secret deal to end the nuclear threat from Iran - behind the backs of his closest allies. Secretary of state John Kerry tells how he worked through the night, with President Obama on the phone, to secure the outlines of the deal.

BBC News takes a look at some of the more dramatic feuds over wills and estates of well-known figures that have taken place over the decades.

Louis Theroux travels to Johannesburg, where the residents find themselves increasingly besieged by crime. Despairing of the capability of the police and the courts to protect them, many have turned to an industry of private security, offering protection for a price. Are the sometimes brutal methods of these private police really a solution or just another part of the problem?

The first stop for Louis is a meeting with William Mayangoni, the local co-ordinator for a security firm known as Mapogo. Based on the outskirts of Diepsloot, one of the squatter camps that ring Johannesburg, William investigates thefts for his mainly white clients. When he catches a suspect, he gives them 'medicine': the alleged offender is beaten with a leather whip known as a sjambok.

Although his clients seem to support what they see as 'an African solution to an African problem', William's methods alienate the people of Diepsloot. Finally, their patience snaps dramatically, and William has to call out the real police in order to protect himself from the vicious threat of the mob.

In the centre of Johannesburg, a security company called Bad Boyz work in an area called Hillbrow, notorious for its high crime rate. Louis meets company director Hendrik De Klerk who explains that much of their activity involves reclaiming and securing buildings that have been taken over, or hijacked, by criminal gangs who illegally take rent from tenants. Louis watches dramatic evictions unfold, in which the police and security companies are not afraid to use force to kick out the protesting residents.
