The UK Government is facing a series of difficult questions after it surfaced that it has chosen to intervene on behalf of Royal Dutch Shell in a major US court case brought against the oil giant by Nigerian villagers. Kiobel v Shell is the latest incarnation of a long-running legal battle fought by communities in the Niger Delta, who claim that Shell is responsible for serious human rights abuses and environmental damage in the region. The Corporate Responsibility (CORE) Coalition, a group of human rights, development and environmental NGOs, is now determined to find out why the UK Government has chosen to intervene and has submitted a wide range of formal Freedom of Information requests.

'Women and girls have been victims of sexual abuse including gang rape, and of sexual exploitation,' the group said in a report based on 211 interviews conducted since 2009. Angola has deported around 400,000 illegal immigrants - most from the Democratic Republic of Congo (DRC) - since 2003, according to UN data.

Twenty-five mutineers loyal to a renegade general have been killed in clashes with the army in eastern Democratic Republic of Congo, the government said. The east of the Central African country remains unstable nearly a decade after the formal end of a vicious civil war which sucked in neighbouring countries and left millions dead. The region has been swept by fresh fighting in recent weeks after hundreds of troops defected from the army over issues including poor pay and living conditions and in support for Bosco Ntaganda, who is wanted by the International Criminal Court for war crimes.

Fresh clashes between the DR Congo's army and a group of mutineers erupted Sunday in the eastern province of Nord-Kivu, defectors said, a day after fierce battles near a gorilla park. 'We're on the ground.

Africa's impressive growth during the financial and economic crisis of the last five years will be put at risk unless action is taken to combat rising inequality, according to the annual health check on the continent from a panel led by the former UN secretary general Kofi Annan. The report from the Africa Progress Panel found that African countries were growing consistently faster than almost any other region, with booming exports and more foreign investment. But it warned that there was a contrast between a growing yet still relatively small middle class and the Africans left behind after a decade of buoyant activity.

A Somaliland military court has sentenced 17 people to death and jailed five others for life following what it said was their role in attacking an army base. The ruling by the court sitting in Hargeisa, some 1,500 kilometres northwest of Mogadishu were immediately seen as harsh and raised concerns over its impartiality given the speedy delivery and absence of independent lawyers for those charged.

The Disarmament, Demobilization and Reintegration (DDR) process relating to former rebels in the Central African Republic (CAR) is back on track: More than 1,000 already disarmed fighters of the Popular Army for the Restoration of Democracy (APRD) led by Jean Jacques Démafouth began to be demobilized on 12-13 May. APRD says 1,431 disarmed ex-combatants were demobilized on 12 May in the northern-central prefecture of Nana Gribizi in the presence of the Central African Armed Forces; representatives of the Mission for the Consolidation of Peace Central Africa (MICOPAX); Jean Jacques Démafouth in his capacity as senior vice-president of the DDR Steering Committee; and CAR Disarmament Minister Gen Xavier Sylvestre Yagaongo (second vice-chairman of the committee). The process is due to take a week to complete.

New data released by the World Health Organisation (WHO) titled, 'World Health Statistics 2012 Report' has focused on the growing problem of the non-communicable diseases burden. According to the report, one in three adults worldwide has raised blood pressure, a condition that causes around half of all deaths from stroke and heart disease; while one in 10 adults has diabetes. WHO Director-General Dr. Margaret Chan, said: 'This report is further evidence of the dramatic increase in the conditions that trigger heart disease and other chronic illnesses, particularly in low-and middle-income countries. In some African countries, as much as half the adult population has high blood pressure.' And although no new case of the Wild Polio Virus (WPV) was reported in the last two weeks in Nigeria, the country accounts for 56 per cent of global cases recorded in 2012.

'Survival has received several reports that a large group of police officers have set up a permanent camp close to the community of Metsiamenong, which famously resisted Botswana’s brutal evictions.'

During almost 20 years of exile in Guinea, Joseph did not know if his family was alive or dead. When he recently found out by chance that they had survived the attack that caused him to flee his native Liberia, he decided he must go back. 'For the first time, I am eager to return home. I want to see my family,' said the 55-year-old fisherman, who is joining a growing number of Liberian refugees who are returning home with UNHCR help before they lose refugee status.

South Africa has been urged to deal with the situation at its border with Zimbabwe, which an activist has described as ‘chaos’. There are ongoing reports of victimisation and violence at the border where thousands of Zimbabweans cross between the two countries every week. While many of the crossings are legal, others continue to be done illegally, with Zimbabweans still risking jumping the border into South Africa to flee the situation back home.

This Amnesty International report looks at the crisis in Mali over the last five months. 'Since the beginning of 2012, Mali has been faced with the worst crisis of its recent history, one that has questioned both the integrity of its territory as well as almost 20 years of political stability. A Tuareg rebellion, fueled by fighters arriving from Libya after the fall of Mouammar Gaddafi, launched attacks against the Malian garrisons in the North of the country in early January 2012. The armed groups also committed serious infringements of international humanitarian law by executing the soldiers they caught in combat. The Malian army responded by bombing indiscriminately the civilian population.'
