80 U.S troops to search for Chibok girls

The United States deployed 80 members of its armed forces to Chad to help in the search for the kidnapped Nigerian schoolgirls, the White House said Wednesday.

"These personnel will support the operation of intelligence, surveillance and reconnaissance aircraft for missions over northern Nigeria and the surrounding area," it said in a letter.

"The force will remain in Chad until its support in resolving the kidnapping situation is no longer required."
