Liberia UNMIL mission: UN hands control of security back to government

President Ellen Johnson Sirleaf leads the celebrations with control of security in Liberia back in the government's hands for the first time in 13 years. In Kenya, a first wave of Somali refugees leaves Dadaab refugee camp, amid a controversial move to reduce its size. And as a plastic bag ban comes into force here in France, Tunisia makes the same move in a bid to tackle environmental degradation.
