12 barangays that were not on Basilan Island seceded to form the municipality of Tabuan-Lasa through Muslim Mindanao Autonomy Act No. 187,^[5] which was subsequently ratified in a plebiscite held on March 29, 2008.

History

On August 2, 1993, vice mayor Sattaman Hataman was seriously injured in an ambush by Muslim rebels whilst riding a jeep home with his family and bodyguards; his wife Nora and daughter Hasma were killed during the attack, while a bodyguard was held hostage.^[6]

On December 4, 1995, former mayor Abdulgafor Abubakar was about to ride his motorcycle parked near the Isabela Central Elementary Pilot School in Ilagan, Isabela when he was assassinated by two gunmen. Though he was rushed to a nearby hospital, Abubakar died from his wounds an hour after the shooting.^[7] In the early morning of October 14, 1996, a bomb exploded under the house of mayor Abdulati Tahajid in Barangay Guiong, who had been sleeping in a different house nearby with his family and thus managed to avoid the explosion.^[8]
