Nigeria's military is offering about $1.8 million in rewards for information leading to the arrest of top members of a radical Islamist sect that has killed hundreds of people in the country this year alone.

Lt. Col. Sagir Musa said in a statement Friday the bounty for Boko Haram sect leader Abubakar Shekau is $312,500.

The statement says information on four other named top sect officials would earn the informant $156,000 each. It then listed 14 "commanders" and each had a $62,500 bounty.

The statement gave three phone numbers and said callers' identities would be protected.

Boko Haram, which has launched attacks on mosques, churches, schools, phone masts and government buildings, is held responsible for more than 760 deaths this year alone, according to an Associated Press count.
