The arrests took place Tuesday, three days after a streak of shootings and bombings that killed more than 200 people. CNN reports some of the suspects resisted and fired on arresting officers; however, no casualties have been reported.
U.S. State Department spokeswoman Victoria Nuland urged Nigerians to stand against "enemies of civility and peace." She told Voice of America that U.S. counter-terrorism officials are meeting with Nigerian forces as a part of a regional collaboration to end Boko Haram's violent attacks.
"Obviously we were comparing analyses of the threat, and we were talking about how we might strengthen cooperation so that we can better help the Nigerian government get its arms around Boko Haram," she said. "We are also sending a message very strongly to all people of Nigeria to settle their issues peacefully and respectfully of each other's differences."
