KANO: More than 24 hours after Nigerian officials claimed to have reached a deal with Boko Haram militants to free more than 200 schoolgirls, relatives of the teenagers were still anxiously waiting for news about their return.

Senior government and military officials on Friday said they had struck a ceasefire agreement with the militants ravaging the country's north.

The deal reportedly included the release of the 219 girls whom the extremists seized from their school in April in a case that drew global outrage and sparked a #BringBackOurGirls campaign that included the likes of US First Lady Michelle Obama and Pakistani Nobel Peace laureate Malala Yousafzai.

But there was still no confirmation from Boko Haram's leader and some senior Nigerian officials have questioned the claim.

Reports on Saturday of attacks by gunmen believed to be Boko Haram militants in Abadam, a town near the border with Niger, further threw the purported truce into doubt. The claims could not be independently verified.

A precedent of previous government and military claims about an end to the deadly five-year conflict and the fate of the missing teenagers have also left the relatives cautious.

“We hope it is not deception because we have some doubt,” Enoch Mark told AFP from Chibok – the town where the girls, including his daughter and two nieces, were kidnapped.

“This is what we have been itching to hear for the past six months,” said Ayuba Chibok, whose niece is among those seized. “My prayer is that the two sides will honour the agreement.”

Friday's announcement was made by Chief of Defence Staff Air Marshal Alex Badehand and Hassan Tukur, a senior aide to President Goodluck Jonathan.

But the Nigerian government's own security spokesman, Mike Omeri, said that no deal had yet been reached on releasing the girls.

And Ralph Bello-Fadile an advisor to Nigeria's National Security Advisor (NSA), cautioned that the NSA has been inundated with fraudsters claiming to represent Boko Haram leader Abubakar Shekau.

The United States said it could not confirm whether a deal had taken place.

Jonathan is expected to declare his bid for re-election in the coming weeks, and positive news about the hostages and the violence would likely give him a political boost.
