President Obama has informed Congress today that approximately 80 troops have been sent to Chad in a “support” capacity to take part in the search for 276 kidnapped Nigerian schoolgirls.

The troops, mostly Air Force personnel, will handle surveillance flights and drone flights over the area along the Chad-Nigeria border, where the girls are believed to be held.

The Predator drones are now being flown out of the Chad capital of N’Djamena, and officials say the troops maintaining those drones will remain until the kidnapping situation is resolved.

US flights have been scanning the area for 10 days, and have provided no details on what, if anything, they’ve found during that time.
