Nigeria abducted girls 'sighted', says state governor

The governor of Nigeria's Borno state says he has information on the whereabouts of about 200 schoolgirls kidnapped by Islamist group Boko Haram.

Governor Kashim Shettima said he had passed reports of the sightings of the girls to the military for verification.

Mr Shettima added that he did not think the girls had been taken across the border to Chad or Cameroon.

Earlier, France's president offered to host a summit on Boko Haram.

"I suggested, with Nigerian President Goodluck Jonathan, a meeting of Nigeria's neighbouring countries" Francois Hollande said.

"If the countries agree, it should take place next Saturday" he added.

Countries neighbouring Nigeria, such as Cameroon, Niger and Chad, would be invited to the security summit.

Aides said the US, UK and EU would also be likely to attend.

The US, UK and France have already pledged technical assistance to the Nigerian government.

Meanwhile, President Jonathan said an Israeli counter-terrorism team would arrive in Nigeria to help in searching for the schoolgirls, who were abducted last month.

'Slaves'

French troops entered Mali last year to push out al-Qaeda affiliated militants.

Both the US and UK distanced themselves from suggestions that they would send soldiers to take part in the military operation in the vast north of Nigeria.

"There's no intention at this point to be putting any American boots on the ground" said US Defence Secretary Chuck Hagel on Sunday.

UK Prime Minister David Cameron said it was unlikely Nigeria would ask for British troops to help, but he added: "I said to President Jonathan where we can help, please ask, and we will see what we can do."

"I rang the Nigerian president to offer anything that would be helpful and we agreed to send out a team that includes some counter-terrorism and intelligence experts to work alongside the bigger American team that's going out there."

Mr Cameron later tweeted his support for a hashtag aimed at raising awareness of the abductions.
