On 16 September 2007 private security guards employed by the American firm Blackwater opened fire on civilians in Baghdad's Nisour Square. Seventeen Iraqis were killed, and another 20 injured.

Over four years, with intensive negotiations with multiple parties and even support from the Irish rock star Bono, in 2010 the World Bank and International Monetary Fund announced they would forgive 4.6 billion dollars of the country’s debt.Bob Howard speaks to former president Johnson Sirleaf about the long road to debt forgiveness.

For more than 20 years, people in Belarus have been protesting against the authoritarian rule of President Alexander Lukashenko - who's been dubbed Europe's last dictator. Lukashenko came to power in a landslide election victory in 1994 but he soon changed the constitution to give himself sweeping new powers. He has remained in office ever since, winning elections which observers say are rigged. Opponents of the regime have faced harassment, violence and arrest. Some are believed to have been kidnapped and murdered by the state. Alex Last has been speaking to the exiled dissident and co-founder of the Belarus Free Theatre, Nikolai Khalezin, about the origins of the protest movement in Belarus.Photo: A banner compares Belarusian President Alexander Lukashenko to Stalin and Hitler, during a protest march in Minsk, Belarus, March 15, 2000 (Getty Images)

The USA is the only rich democracy not to provide universal healthcare. After WW2 US President Harry Truman was horrified that only a fifth of all Americans could afford proper healthcare. Most middle class Americans had no private health insurance and many found medical fees unaffordable. He calculated that more than 300,000 people died every year because they couldn't pay for proper treatment. In 1945 he tried to persuade Congress to push through legislation for an insurance programme meaning all workers would pay for their healthcare through a monthly fee or tax. But the American Medical Association - representing doctors - employed a public relations firm to lobby against the move. Claire Bowes has been listening to archive material of Harry Truman and speaking to Jonathan Oberlander a Professor at the University of North Carolina, Chapel Hill.

In October 2010, Haiti was hit by an outbreak of cholera, the first in recent history of the impoverished Caribbean nation. Nepalese peacekeepers belonging to the international MINUSTAH mission were blamed for introducing the deadly disease, but for many years the UN refused to accept any responsability. More than 10,000 Haitians have died from cholera, and thousands more were infected. The UN finally apologised to the Haitian people in December 2016. Mike Lanchin speaks to the French specialist in tropical medicine and infectious diseases, Dr Renaud Piarroux, whose investigation helped force the UN's hand.Photo: Haitians wait for medical treatment for cholera, Oct 22 2010 (REUTERS/St-Felix Evens)

The Voting Rights Act of 1965, a landmark civil rights-era electoral law was designed to protect African-American and other minority voters. It was introduced to remove the many obstacles that were in place to prevent African-Americans from being able to vote. Many states, particularly in the south, used intimidation, local laws and so-called literacy tests to prevent black people from being able to register to vote. In 2010 Shelby County in Alabama attempted to overturn a key part of the law. In 2013 the US Supreme Court upheld their challenge. Now voters who are discriminated against bear the burden of proving they are disenfranchised.
