American troops sent to Nigeria to assist efforts to find the kidnapped Nigerian schoolgirls.

The United States has deployed 80 American troops to Chad to assist in the search for more than 200 Nigerian schoolgirls kidnapped by the militant group Boko Haram last month, President Barack Obama told Congress on Wednesday.

“These personnel will support the operation of intelligence, surveillance, and reconnaissance aircraft for missions over northern Nigeria and the surrounding area,” Obama wrote in a letter to House Speaker John Boehner and Senate President Pro Tempore Patrick Leahy. “The force will remain in Chad until its support in resolving the kidnapping situation is no longer required.”
