Burundi's President Nkurunziza: First a third term, now a seven-year mandates Image copyright AFP Image caption Pierre Nkurunziza has been president since 2005 Burundi goes to the polls on 17 May to vote in a constitutional referendum, which could extend President Pierre Nkurunziza's rule to 2034. Here's why the vote has become a contentious issue:
Who is President Nkurunziza?He is a former rebel leader who came to power at the end of Burundi's ethnically-charged civil war in 2005.
His run for a controversial third term in 2015 set off a wave of violence and an attempted coup, which was foiled by government forces. The political crisis led to hundreds of deaths, and more than 400,000 people fled the country, according to the UN.

Kenya, Uganda and Tanzania in anti-fake news campaign Image copyright AFP Image caption President Kenyatta says the new law will help prosecute cyber criminals A new law in Kenya will punish the spreading of "false information" and impose a lengthy jail term on offenders.
It proposes a fine of $50,000 (£37,000) and/or up to two years in prison for publishing "false" information.
The Computer Misuse and Cybercrimes law also criminalises abuse on social media and cyber bullying.
However, the Committee to Protect Journalists ( CPJ) says the bill would stifle press freedom.
The rights body had urged President Uhuru Kenyatta to send back the bill to parliament to remove clauses that it says violated freedom of expression.
CPJ said that parts of the law criminalised unauthorised access and sharing of government data which would remove protection for whistle-blowers.
According to Kenya's Editor's Guild, the law "may be abused by state authorities to curtail media freedom".
Ghanaian shoe seller vows to bring Jammeh to justice A Ghanaian man is leading a campaign to bring The Gambia's ex-ruler Yahya Jammeh to justice over the murder of 56 migrants who were mistaken for coup plotters, writes the BBC's Alex Duval Smith.
Martin Kyere leapt from the pick-up truck into the darkness. Bullets whistled around him as he ran for his life through the thick Gambian forest. He fell. He picked himself up. He dodged the soldiers' searchlight. He promised himself not to rest until Mr Jammeh was brought to justice.
Thirteen years later and living in his native Ghana, Mr Kyere is the key witness in an international effort to bring The Gambia's former president to trial for what was probably the single largest mass killing during the 22-year reign of terror.
Meanwhile, Mr Jammeh has lived in Equatorial Guinea since January 2017. He went into exile there under a regionally-brokered deal after losing the December 2016 presidential election to Adama Barrow...
Sam Nzima: The man behind the iconic photo of the fight against apartheid Image copyright Getty Images Image caption A woman holds the iconic photograph taken by legendary photographer Sam Nzima in 1976 South African photographer Sam Nzima dashed to the scene of a shooting during the June 1976 students' uprising against apartheid just in time to see a child falling to the ground.
It was when another student picked up the dying 13-year-old Hector Pieterson that Nzima clicked to take one of the most iconic photographs in history, becoming a symbol of the brutality of the white minority regime, which flashed around the world.
In a 2010 BBC interview, Nzima, who has died aged 83, recalled: "I didn't know who it was. I saw a child falling down.
"I rushed there with my camera.
"And I saw another young man pick him up and as soon as he had picked him up, I started shooting the pictures.
"It was a very high risk because this picture was taken under a shower of bullets," he said.
DR Congo: Why tourists go to Virunga National Park Image copyright Getty Images Image caption Mountain gorillas are one of Virunga's main attractions One of Africa's most stunning parks - Virunga in the Democratic Republic of Congo - has suffered a major blow following the killing of a ranger, and the abduction of two British tourists, who were later released.
The attack has forced the park's boss - Belgian prince Emmanuel de Merode - to announce a suspension of tourism.
This will be another setback to efforts to earn much-needed income to protect the World Heritage Site from the lawlessness that has gripped the region since the fall of long-serving ruler Mobutu Sese Seko more than two decades ago.
How dangerous is Virunga?Boasting Africa's most diverse wildlife, Virunga - which stretches across 7,800 sq km (3,000 sq miles) - is one of the most dangerous parks on the continent.
The extent of the threat is reflected by the fact that between 1,500 and 2,000 armed f..
