When Moktar Belmokhtar, military commander of Al-Qaeda in the Maghreb, left AQIM over ideological and operational differences, he oversaw the formation of two new groups, the Tuareg Brigade Mali and Signers in Blood Brigade, in addition to the Masked Battalion that he formed in 2007. It is unclear what the relationship between the groups might be.
In January 2013, the brigade took more than 800 people hostage at the Tigantourine gas facility in Algeria. Thirty-nine hostages were executed and one Algerian killed before the facility was recaptured by Algerian forces, who killed 29 members of the brigade.
