Sayyaf guerrillas occupied the Malaysian dive resort island Sipadan and took 21 hostages, including 10 tourists and 11 resort workers – 19 foreign nationals in total. The hostages were taken to an Abu Sayyaf base in Jolo. Two Muslim Malaysians were released soon after. Abu Sayyaf made various demands for the release of several prisoners, including 1993 World Trade Center bomber Ramzi Yousef and $2.4 million. In July, a Filipino television evangelist and 12 of members of the Jesus Miracle Crusade Church offered their help and went as mediators for the relief of other hostages. They, three French television crew members and a German journalist, all visiting Abu Sayyaf on Jolo, were also taken hostage. Most hostages were released in August and September 2000, partly due to mediation by Libyan leader Muammar Gaddafi and an offer of $25 million in "development aid". Abu Sayyaf conducted a second raid on the island of Pandanan near Sipadan on September 10 and seized three more Malaysians. The Philippine army launched a major offensive on September 16, 2000, rescuing all remaining hostages, except Filipino dive instructor Roland Ullah. He was freed in 2003. Abu Sayyaf coordinated with the Chinese 14K Triad gang in carrying out the kidnappings. The 14K Triad has militarily supported Abu Sayyaf. 2013 Pom Pom kidnappings On November 15, 2013, Abu Sayyaf militants raided a resort on the Malaysian island of Pom Pom. During the ambush, Taiwanese citizen Chang An-wei was kidnapped and her husband, Hsu Li-min, was killed. Chang was taken to the Sulu Archipelago. Chang was freed in Sulu Province and returned to Taiwan on December 21. 2014 Singamata, Baik Island and Kampung Air Sapang kidnappings On April 2, 2014, a kidnap gang believed to originate from Abu Sayyaf militants raided Singamata Reef Resort off Semporna. Chinese tourist Gao Huayun from Shanghai and Filipino resort worker Marcy Dayawan were abducted and taken to the Sulu Archipelago. The two hostages were later rescued after a collaboration between Malaysian and Philippines security forces. On May 6, five Abu Sayyaf gunmen raided a Malaysian fish farm on Baik Island Sabah, kidnapped the fish farm manager and took him to Jolo island. He was freed in July with the help of Malaysian negotiators. On June 16, two gunmen believed to be from Abu Sayyaf kidnapped a Chinese fish farm manager and one Filipino worker in Kampung Air Sapang.
