A team of US experts has been sent to Nigeria to help find more than 200 schoolgirls abducted last month by the Islamist militant group Boko Haram.

US President Barack Obama said the team comprised personnel from military, law enforcement and other agencies.

He said he hoped the kidnapping might galvanise the international community to take action against Boko Haram.
