Equatorial Guinea's tough President Teodoro Obiang Nguema seized power almost 37 years ago from a feared and ruthless uncle and has steered the tiny but now oil-rich nation with an iron glove.

Looking out from the Syrian capital these days, one can understand why President Bashar Assad would be in no hurry to make concessions at peace talks in Geneva, let alone consider stepping down as the opposition demands.

In Damascus, it is easy to forget the war. The airstrikes, the ruins and starvation, sometimes only few miles away, seem distant and unseen. Since a partial cease-fire went into effect at the end of February, the mortar shells from opposition-held suburbs have all but stopped.

In a country awash with guns, a faltering peace deal aimed at ending over two years of intense civil war in South Sudan came down to a dispute over just two dozen weapons.

Clutching rifles under a bright spring sun, the men are among thousands undergoing obligatory nine-month training to join the Autonomous Protection Forces.

Iran may technically be open to foreign investors after a nuclear deal with Western powers, but many sanctions remain, deterring potential business partners who fear the U.S. could hit them again with punishing fines.

Ukraine will next week mark the 30th anniversary of the Chernobyl disaster, when human error and flawed Soviet reactor technology led to the world's worst nuclear accident.

Ahead of the April 26 anniversary, AFP looks at the steps taken since 1986 to improve nuclear safety around the world and -- as Fukushima showed in 2011 -- the challenges that remain.

With Sunday's vote in the lower house of Congress to authorize the Senate to open an impeachment trial against President Dilma Rousseff, Brazil's political crisis enters ever deeper crisis.
