A bomb has exploded outside a stadium in northern Nigeria, killing three people, shortly after President Goodluck Jonathan addressed an election campaign rally there. Police said a female suicide bomber blew herself inside a car, killing herself and another female passenger. Eighteen people were injured. Will Ross reports from Lagos.
The bomb exploded outside the stadium in Gombe just minutes after President Goodluck Jonathan's convoy had left the area. It may not have been as large as other car bombings in Nigeria, but the timing of the attack will have shocked the security forces. The violence is escalating in the run-up to elections due in less than two weeks' time. The attacks are blamed on the jihadist group Boko Haram, which is against democracy and says it wants to set up a caliphate. Over the weekend there were two other explosions in Gombe and another in the city of Potiskum.
Military aircraft belonging to the Chadian armed forces have attacked Boko Haram positions in northeastern Nigeria for a third day. Eyewitnesses say Chadian jets and helicopters bombed and strafed targets in the town of Gamboru, just across the border from Cameroon.
Dominique Strauss-Kahn, the former head of the International Monetary Fund, has gone on trial in France on charges of helping to procure women for sex parties. Mr Strauss-Kahn was forced to abandon his political career in France after being accused by a chambermaid of attempted rape four years ago. From Paris Lucy Williamson.
The man once tipped to be France's next president appeared at the Lille courthouse today, zipping past reporters gathered to capture his latest public scandal.

But a lawyer for the former IMF chief says that while he attended the parties he had no knowledge of the women's background nor any organisational role.
President Obama has presented a four-trillion-dollar budget for the coming year, setting out plans to help the middle class at the cost of higher taxes on companies and on the wealthiest Americans. Correspondents say the president is trying to set the political agenda for the rest of his term in office. But it's likely to be oppressed by the Republican-controlled Congress. From Washington here is our correspondent Gary O'Donoghue.
President Obama has thrown down the gauntlet to the new Republican Congress - his explicitly tight plans for extra defence spending, something his opponents want through raising taxes for roads, bridges and high-speed Internet, something they will take issue with. But it's the tax rises that will prove most controversial, in particular the plan to impose a one-off levy on the overseas profits of US corporations, which could raise almost a quarter of a trillion dollars.
