Nigeria's military say it has reprieved 66 soldiers sentenced to death for mutiny and trying to kill their commanding officer in the war on Boko Haram. Instead, they will be jailed for 10 years.

A statement Saturday says Army Chief Gen. Tukur Buratai made the decision. The 66 mutinied after dozens of soldiers died in a Boko Haram ambush, after being ordered against their will to drive down a dangerous road at night.

The military says it is also reviewing other cases, including 579 soldiers secretly tried in May.

The reprieves come as a former presidential adviser on national security is on trial for allegedly diverting $2.1 billion meant to buy arms for ill-equipped troops who told the AP they were sent into battle with just 30 bullets each.
