"The Abu Nidal Organization—named for its leader Sabri al-Banna, a veteran Palestinian terrorist known by the nom de guerre Abu Nidal—is a secular international terrorist group that has been sponsored by Syria, Libya, and Iraq, and has attacked a wide range of Western, Israeli, and Arab targets. Over the years, the Abu Nidal Organization (ANO) mounted terrorist operations in twenty countries, killing about three hundred people and wounding hundreds more. In the mid-1980s, the group was seen as the world’s most dangerous terrorist organization, but some experts say the group is inactive and no longer poses much of a threat."
