The attack was staged at around 06:00 a.m. local time in Sumisip, Basilan Province, Inquirer quoted the Western Mindanao Command of the Armed Forces of the Philippines as saying. The four wounded include a soldier and three members of the Civilian Armed Auxiliary (CAA) during the attack on the outpost in a village, Westmincom spokesperson Lieutenant Esteffani Cacho said. 'The soldier and the CAAs were manning the temporary checkpoint when Abu Sayyaf gunmen staged the harassment,' Cacho said. The 380-strong Abu Sayyaf group, founded in early 1990s by Islamic extremists, is notorious for kidnappings, bombings and even beheadings in southern Philippines over the past decade.
