President Obama says Russia has put itself on the wrong side of history by violating Ukraine's sovereignty. He told reporters of the White House that the US was looking at a diplomatic and economic measures intended to isolate Russia.

Concerned by how the circle of violence in the Central African Republic could spiral into genocide, the UN has proposed a peacekeeping force for this war-torn country. Right now, thousands of African Union and French troops are in the country,which will soon be bolstered by soldiers from the European Union. But the UN Secretary General Ban Ki-moon would like to see a blue-helmeted peacekeeping force of up to 10,000 soldiers and 18,000 police. It would include troops from the African Union already on the ground. He would like the force to be given a robust mandate and also adequate resources.
