Nigeria: "All options are open" in bid to rescue abducted schoolgirls

ABUJA, Nigeria -- A Nigerian government official said "all options are open" in efforts to rescue almost 300 abducted schoolgirls from their Islamic extremist captors as U.S. surveillance and reconnaissance aircraft started flying over the West African country.

Boko Haram, the militant group that is holding some 276 female students it kidnapped last month from a boarding school in northeast Nigeria, said the girls will only be freed after the government releases jailed militants.

On Monday, for the first time, their kidnappers put out video of the girls. Asked how the Nigerian government would respond to the video, Interior Minister Moro Abba told CBS News the government does not negotiate with terrorists. But he also said a process of dialogue continues. So they haven't closed the door on negotiating a release.

Mike Omeri, the director of the government's information agency, called the National Orientation Agency, said the government will "use whatever kind of action" it takes to free the girls. He also warned that a military operation, with foreign help, was possible.

"At the moment, because all options are open we are interacting with experts, military and intelligence experts from other parts of the world," he said late Monday. "So these are part of the options that are available to us and many more."

Boko Haram, which wants to impose Islamic law on Nigeria, has killed more than 1,500 people this year in a campaign of bombings and massacres, despite a state of emergency that was declared in three northeastern Nigerian states, giving security forces special powers.

The rights group Amnesty International says Nigeria's military had advance warning of a possible Boko Haram attack before the April 15 kidnappings in Chibok, in the northeastern Borno state, but did not react because of their fear of engaging the extremists. More than 300 schoolgirls were abducted, according to police, and they are believed to be held in the vast Sambisa Forest, some 20 miles (about 30 kilometers) from Chibok. Boko Haram's leader has threatened to sell the girls into slavery.

Hannah, a girl who was kidnapped last year, was held hostage for more than two months in a Boko Haram stronghold in the forest. She told CBS News she was beaten regularly during this time for refusing to convert to Islam.

"They tied a rope around my neck and pulled me on the ground," she said, "while they kept telling me that they would slaughter me."

The mass abductions and failure of Nigeria's government and military to rescue the girls has aroused outrage at home and abroad.

The White House said Monday that the U.S. team assisting the Nigerian government is made up of nearly 30 people from the State and Defense departments, as well as the FBI, including 10 Defense Department planners who were already in Nigeria and were redirected to assist the government.

Another seven Defense Department personnel were sent to Nigeria from AFRICOM, the U.S. Africa Command based in Germany, said White House spokesman Jay Carney.

The U.S. is also sharing commercial satellite imagery with the Nigerian government and is flying manned intelligence, surveillance and reconnaissance aircraft over Nigeria with the Nigerian government's permission, a senior U.S. official told The Associated Press on Monday.
