Fears grew in northeast Nigeria on Wednesday about the fate of potentially scores of girls who have not been seen since a Boko Haram attack on their school two days ago.

Militants stormed the Government Girls Science Secondary School in Dapchi, Yobe state, on Monday evening. Locals initially said the girls and their teachers fled the attack, wrote dailymail.co.uk

The jihadists gained worldwide notoriety in April 2014 when they abducted 276 girls from their school in Chibok, in neighbouring Borno state.

Last month the group, led by Abubakar Shekau, released a new video of the kidnapped schoolgirls claiming they do not want to return to their parents 

Fifty-seven escaped in the immediate aftermath and since May last year, 107 have either escaped or been released as part of a government-brokered deal. A total of 112 are still being held.

Monday's incident sparked fears of a repeat of Chibok and on Wednesday morning some 50 parents and guardians gathered at the school demanding information.

'Our girls have been missing for two days and we don't know their whereabouts,' Abubakar Shehu, whose niece is among those missing, told AFP.

'Although we were told they had run to some villages, we have been to all these villages mentioned without any luck. We are beginning to harbor fears the worst might have happened.

'We have the fear that we are dealing with another Chibok scenario.'

According to school staff, there were 710 students at the state-run boarding school, which caters for girls aged 11 and above.

Inuwa Mohammed, whose 16-year-old daughter, Falmata, is also missing, said it was a confused picture and that parents had been frantically searching surrounding villages.

'Nobody is telling us anything officially,' he said. 'We still don't know how many of our daughters were recovered and how many are still missing.

'We have been hearing many numbers, between 67 and 94.'

Police in the state, which is one of three in the northeast Nigeria worst-affected by the Boko Haram insurgency, said they had no reports of abductions following the attack.

Yobe's education commissioner, Mohammed Lamin, said the school had been shut and a rollcall of all the girls who have returned was being conducted.

'It is only after the head-count that we will be able to say whether any girls were taken,' he said.

Some of the girls had fled to villages up to 30 kilometers away through the remote bushland, he added.  

In the Boko Haram video 14 of the abducted girls - three carrying babies - can be seen in the clip, nearly four years after they were seized from the northeast Nigerian town.

But despite a concerted global campaign for their release, and talks between the government and the militants, the girls shown in the recording vowed not to return home.

The Chibok abductees are among thousands of women, girls and boys kidnapped during the conflict, which began in 2009 and has killed at least 20,000 people and displaced more than 2.6 million.
