Nigeria's military says it has reinstated more than 3,000 soldiers who were dismissed from the army for alleged indiscipline ?in the ongoing war with Boko Haram Islamic extremists in the northeast of the country.

Army spokesman Col. Sani Usman said Thursday that a panel set up to review the cases recommended reinstatement of 3,032 soldiers out of the 5,000 cases that were reviewed.

The reinstated soldiers have shown their total readiness to be re-launched into combat and have commenced a retraining exercise at the Nigerian Army Training Center in Kotangora, Usman said.

Nearly 20,000 people have died in Boko Haram's six-year-old uprising.
