In 2002, Iran announced that it believed Sadr was killed by Libyan agents, though opinions on the imam's fate vary widely. To this day, Colonel Qadhafi maintains that Sadr returned safely from Libya and that he knows nothing about the imam's current location. The Black Brigade disappeared in the mid-1980s, and its members most likely were absorbed by larger Shia terrorist groups such as Hezbollah. For these reasons, attacks claimed by the Black Brigade are very unlikely to reappear, though attacks in the name of the imam may continue.

The Black December terrorist group operated briefly during 1973. Carrying out attacks in England and Afghanistan, the group targeted Indian diplomatic and private interests with the aim of gaining the release of Pakistani prisoners of war from Indian detention. India and Pakistan fought a war in 1971, stemming from Indian intervention in the Pakistani Civil War that eventually led to the separation of East Pakistan and establishment of the independent nation of Bangladesh. The war ended in a Pakistani defeat in December 1971, the most likely inspiration for Black December's name. India and Pakistan also fought in 1965 and soon after the British withdrawal and subsequent partition in 1947, and tensions between them continue to remain high, primarily over the status of Kashmir.

Black December was not heard from since 1973 until 1997, when a letter was received at a British diplomatic mission in Pakistan threatening the lives of members of the visiting Indian cricket squad. In their letter Black December, or simply unaffiliated individuals professing to represent the long-inactive organization, threatened to carry out attacks unless those responsible for the group's 1973 shooting in London were released. No violent action occurred, however, and Black December is not viewed as a current terrorist threat.

Black Friday claimed responsibility for planting a bomb outside of the Saudi Arabian Cultural Mission in Ankara, Turkey on July 21st, 1988. The bomb was discovered and defused before detonating. <P><br /><br />Little else is known about Black Friday. The name and target suggest that it was a pro-Iranian group retaliating for a deadly clash between Iranian pilgrims and Saudi Arabian police during the holy pilgrimage to Mecca (called the hajj in Arabic) on July 31st, 1987. The choice of a Saudi target in Turkey indicates that the members of the group may have been Turkish citizens sympathetic to Iran. Given that the Iranian-Saudi conflict had a great deal to do with sectarian (Sunni-Shia) strife, it is probable that the members of Black Friday were Turkish Shia. Shia make up an unspecified, but small, portion of Turkey's population. <P><br /><br />The 1987 incident in Mecca erupted after Saudi police tried to quell an Iranian-led anti-American demonstration during the pilgrimage. The move sparked a riot, and more than 400 people were killed in the shooting and stampede that followed. 85 of the victims were Saudi policemen. The incident led to a bitter diplomatic spat as Iranian leaders called on Shia Muslims to overthrow the Saudi monarchy. Mobs attacked the Saudi Arabian embassy in Tehran. Saudis blamed Iranian government representatives for intentionally sparking the initial riot. To this day, the Saudis blame the protestors for staging the riot, while the protestors blame the bloodshed on the Saudi's heavy hand in dispersing the crowd. <P><br />
