Nigerian President Goodluck Jonathan has canceled his visit to Chibok, the town where more than 200 schoolgirls were abducted, officials say.
Goodluck Jonathan would stop in Chibok, in the north-east, on his way to a conference in Paris on the threat from Boko Haram militants.
But the visit was called off for security reasons, the officials said.

Goodluck Jonathan – under pressure over his government’s failure to rescue the girls – will fly direct to Paris.
On Thursday, relatives of the girls called for their unconditional release by Boko Haram.
Goodluck Jonathan is said to have ruled out negotiations over a possible release of prisoners.
Nothing was seen of the girls for almost a month after they were taken from Chibok.
But on Monday the group released a video showing more than 100 of them and offering an exchange for prisoners.
President Goodluck Jonathan has been criticized for not visiting Chibok – more than a month after the girls were seized.
The president will travel to Paris to take part in a summit convened by French President Francois Hollande to discuss Boko Haram.
The leaders of Nigeria’s neighbors – Benin, Cameroon, Niger and Chad – are scheduled to attend the summit on Saturday, which will also include representatives from the UK, US and EU.
A statement said delegates at the meeting will “discuss fresh strategies for dealing with the security threat posed by Boko Haram and other terrorist groups in west and Central Africa”.
