Boko Haram crisis: Niger to send troops to Nigeria

Niger's parliament has voted to send troops to Nigeria to join the fight against militant Islamist group Boko Haram.

The vote took place after Boko Haram attacked a prison and detonated a car bomb on Monday in the town of Diffa, near Niger's border with Nigeria.

Meanwhile Niger's president has vowed to defeat the militants, as the BBC's Will Ross reports.
