The Battle of Tipo-Tipo was a military engagement that began in 9 April 2016 at Tipo-Tipo, Basilan Island, Philippines between forces of the Philippine Army and members of the Abu Sayyaf militant group. The battle resulted in dozens of casualties, with at least 18 soldiers and 31 militants reported killed, and more than 70 others injured. It was the largest single loss of life for the Philippine Army since the beginning of the year, and came just a day after the group had released an Italian hostage.
