Philippines authorities are hunting two men believed to have planted a bomb that killed two people, including a young girl, at a street festival in the nation’s south on Tuesday, Agence-France Presse reports. The blast coincided with the town’s 61st founding anniversary and occurred while the whole region is under martial rule. One of the suspects reportedly offered fruit to people in hopes of evading suspicion when he abandoned the bag that also contained the bomb, according to the Associated Press. The Islamic State of Iraq and Syria (ISIS) has claimed responsibility for the deadly attack, according to Maryland-based SITE Intelligence Group, a company that tracks the online activity of jihadist and white supremacist organizations.
