President Goodluck Jonathan of Nigeria has declared a state of emergency in three northeastern states in response to increased attacks by the Islamist militant group Boko Haram. In a national television address, Mr. Jonathan said the Nigerian army would take over security in Borno, Yobe and Adamawa states whilst state politicians would remain in their posts.

"The activities of the insurgents and terrorists have been reprehensible causing fear among our citizens and a near-breakdown of law and order in parts of the country, especially in North. We have taken robust steps to unravel and address the root causes of these crises, but it would appear that there is a systematic effort by insurgents and terrorists to destabilize the Nigerian states and test our collective resolve."

A BBC correspondent in Nigeria says it's the first time that President Jonathan has admitted the state is not in control of the whole country.

Alda Gross is neither terminally nor chronically ill, but she is 82 and apparently wants to end her life before she becomes incapacitated. The Swiss assisted suicide organization EXIT refused her. The Swiss Supreme Court ruled against her. But now the European Court of Human Rights has found in her favour.
