Fury, who has not fought since beating Klitschko, replied: "Let's dance."

Tanzania plans to build a 2,100-megawatt hydroelectric plant on a World Heritage site famous for its wildlife habitat despite opposition from environmentalists, Reuters news agency reports.

According to a statement from the Tanzanian president's office, President John Magufuli "wants construction of this project to start as quickly as possible and produce an abundant supply of electricity to speed up the development of the country".

It is believed the project at Stiegler's Gorge in the Selous Game Reserve would help the country end long-term energy shortages.

According to UNESCO the 50,000 sq km designated reserve is one of the largest protected areas in Africa, famous for being home to many animal species.

Ethiopian experts are expected in Tanzania this week to give advice on how the project can proceed. Ethiopia has several hydropower projects under construction, including the Grand Renaissance Dam.

Critics, however, say a hydropower dam along a major river running through the Selous Game Reserve could greatly affect wildlife downstream.

Four police officers and four civilians - reportedly children returning to school after Eid celebrations - were killed after their truck hit a landmine on a road near Kenya's border with Somalia, police said.

It is the second such attack this month, after four police officers and a civilian died in a blast in northeast Kenya on 16 June. At least eight police officers were killed in two roadside bombings in May.

The blast took place in the town of Kiunga.

No group has yet said they were behind the blast, but the Somalia-based al-Shabab militant group - which is fighting to overthrow the Somali government - has said it will continue to attack Kenya unless it withdraws its troops from an African Union peacekeeping mission.

Amnesty Interntional has called for the immediate and unconditional release of a Zimbabwean human rights campaigner and #ThisFlag protest leader Evan Mawarire.

Mr Mawarire, a pastor, was arrested on Monday for addressing a group of medical students protesting fee increases on the country’s largest campus. The demonstration turned violent.

He is charged with disorderly conduct in public and is expected to appear in court on Wednesday.

Mawarire says he was simply praying with the students.

In a statement, Amnesty says the arrest shows that the protest leader continues to be targeted by a government bent on criminalising him for exercising his rights to freedom of expression and peaceful assembly.

In January this year, Mawarire was arrested and charged with subversion and “insulting the national flag of Zimbabwe”. He was later released on bail.

He is the Founder of the #ThisFlag movement and led several anti-government protests in 2016 against corruption and the declining economy.

Parts of Africa could suffer a massive unemployment crisis by 2050, according to new research from the Tony Blair Institute, external.

"This would have serious implications: for the continent and its people, for the prosperity and stability of dozens of countries, and even for the global economy and security," the research found.

The labour force in sub-Saharan Africa will be 823m by 2040, up from 395m in 2015. However, total number of jobs is only expected to hit 773m, leaving 50m people without a job.

The report found that countries with high economic potential - such as Ghana, Kenya, Liberia, Malawi, Nigeria and Sierra Leone - were failing to achieve growth.

It called for governments to pursue "inclusive growth" strategies and said countries such as Botswana, Ethiopia and Mauritius had made significant progress because political leaders had worked alongside stakeholders and development partners.

Simon Mann, an ex-British mercenary, has accused US billionaire George Soros of plotting to overthrow Equatorial Guinea's President Teodoro Obiang Nguema in 2011, AFP news agency is reporting.

Mr Mann, who led a failed coup in 2004 coup against Mr Nguema, is giving testimony at a trial in Paris. He is testifying on behalf of the president's son, Teodorin Obiang.

Mr Obiang is accused of using Equatorial Guinea's wealth to pay for his lavish lifestyle.

He is accused of using over $112m (£87m) from the country's coffers to buy a six-storey luxury mansion on Avenue Foch, in one the most prestigious neighbourhoods in Paris, as well as a set of Italian supercars.

Mr Obiang, who was not in court, has denied the charges. He says his money was legally acquired.

Mr Mann also told the court that a lawyer for the NGO Transparency International, William Bourdon, was part of the plot.

Mr Mann, an Eton-educated former British special forces officer, was arrested in Zimbabwe in 2004 on his way to overthrow President Obiang. He was extradited to Equatorial Guinea in 2008 but pardoned a year later by the president.

AFP says it has not yet got a comment from Mr Soros regarding the testimony given by Mr Mann.

However, Mr Bourdon, who represents civil plaintiffs in the Obiang case on behalf of Transparency International France, has accused Mr Mann of "conduct which had plumbed the depths of filth".

Mr Mann told the court he could not prove his claims as he did not have written evidence.

The London-based think tank, Chatham House, has warned that world food supplies could be put at risk because of the increasing reliance on what it calls transportation choke points.

The organisation has identified fourteen locations around the world, such as the Suez Canal in Egypt, which if they were closed or disrupted would have serious effects on the supply of food and other essentials.

Chatham House says governments need to be prepared for the effects of conflict or environmental change. It adds that the increasing intertwining of transport routes makes any disruption to supply potentially very damaging.
