The Signatories in Blood, an armed unit founded by the one-eyed Mokhtar Belmokhtar last year when he split from Al-Qaeda in the Islamic Maghreb, was designated a foreign terrorist organization by the State Department.
The group, also known as the al-Mulathamun Battalion, "claimed responsibility for the January 2013 attack against a gas facility near In Amenas, Algeria," the department said in a statement, adding that three Americans were among the 38 civilians killed in the siege.
Today's designations bar US citizens and companies from having any dealings with either the Algerian group or al-Shihabi.
