Nigeria is appealing for international help as Islamic extremists, who kidnapped nearly 300 girls, make more threats.
FOX News Radio's Emily Wither reports:
The kidnapped girls have been held captive for nearly a month now -- 53 managed to escape but 276 remain missing. Britian and the U.S. are offering to help. White House Press Secretary Jay Carney says it'll come in the form of counter-terrorism and information-sharing:
(Carney) "This is an outrage and tragedy and we are doing what we can to assist the Nigerian government."
The Nigerian government says they still don't know where the girls are, while the leader of terrorist network Boko Haram, who claims responsibility for the kidnappings, calls them slaves and is threatening to sell them.
