Since he left Yasser Arafat's organization at the end of 1973 (they are now bitter enemies), Abu Nidal has planned and executed over 100 terrorist raids in 18 countries around the world. His organization, which numbers less than 200 active members and a few hundred more who offer aid and support, is possibly the most dangerous underground group in the world. This book describes how Abu Nidal's small band has infiltrated country after country, attacking schools, synagogues, airports, buses, beaches, and houses. Armed with scores of passports, and without radically disguising his face, Abu Nidal travels throughout the world unfettered. Based in Syria and Libya, working openly with Libya's Colonel Muammar el-Qaddafi, Abu Nidal continuously moves between Libya, Iraq, Syria, and South Yemen. All these countries secretly aid Abu Nidal's group. The epilogue reviews American efforts in countering Egypt's release of the Achille Lauro hijackers. Appended supplementary information and 34-item bibliography. (Publisher summary modified)
