Revenge of the Hebrew Babies has not claimed responsibility for an attack since April 2003.  The group was probably made up of a few individuals, and was not a highly-structured terrorist organization.  In any case, Revenge of Hebrew Babies is inactive and will probably not be responsible for further attacks.

Revolutionary Action Organization of the Arab Resistance Front

The Revolutionary Organization of the Arab Resistance Front was a terrorist group responsible for one unsophisticated operation in its history, in which two Polish nationals that worked in Lebanon were wounded in a drive-by shooting. After the attack, a representative of the group claimed responsibility and warned the Polish government to retract its declaration that it would help Soviet Jews move to Israel. The group may be related to the pro-Iran Islamic Jihad for the Liberation of Palestine, who had threatened to attack targets of countries that supported the migration of Jews to Israel just days before the attack. <br /><p><br />Several days after the attack, the group issued a warning to the French government that if the body of Suleiman al-Halabi was not returned to Arab soil, similar attacks on French assets would occur the world over. Al-Halabi is a hero in the Arab world for assassinating a general that Napoleon tasked with colonizing Egypt. In 1800, al-Halabi was killed at the hands of the French, who publicly impaled him on a stake. Martyr Suleiman al-Halabi Unit was an alias of the Revolutionary Organization of the Arab Resistance Front.<br /><p><br />From these facts, it can be inferred that the group is an Arab nationalist, anti-Israel group that opposed Western involvement in Lebanon, if not the greater Middle East.<br />

Despite its threats, the Revolutionary Organization of the Arab Resistance Front committed no further attacks. It can be considered inactive.

On August 29, 1970 the Revolutionary Action Party detonated a bomb in the Portuguese Embassy  to the US, and a second bomb in the Rhodesian Information office, both located in Washington, D.C.  The group was previously unknown and although the Secret Service took the threat seriously enough to place agents at these two locations, the group never initiated any further action.  The Revolutionary Action Party attacked these locations in protest of American support for the apartheid regime in South Africa.
