(CNN) - At least 20 students were killed in northern Nigeria last week when Islamic militants razed their boarding school, prompting British authorities to label the group thought to be responsible, Boko Haram, a terrorist organization.
But the Obama administration has not done the same.
When asked about the attack, a senior Obama administration official said that the United States is "deeply concerned" about extremism in Nigeria, and pointed to the history of cooperation between the U.S. and Nigeria on security issues.
"We are working closely with the Nigerian government to address the growing threat of violent extremism throughout Nigeria," the senior official said, adding that the U.S. also supports vocational training programs to help discourage radicalization and recruitment throughout Nigeria.
