DHAKA: France is to host a security summit on the threat from Boko Haram Islamists, after they abducted more than 200 schoolgirls in Nigeria in April.

Nigerian president Goodluck Jonathan and other West African leaders will attend the talks in Paris.

On Friday Jonathan was due to visit the north-eastern town of Chibok, where the girls were seized, but called it off for security reasons.

He has ruled out negotiations over their possible release, reports say, according to the BBC.

On Thursday, relatives of the girls called for their unconditional release by Boko Haram.

This came three days after Boko Haram released a video showing more than 100 of the girls and offering an exchange for prisoners.

French president Francois Hollande is expected to open the summit later on Saturday.
