The Battle of Tipo-Tipo is an ongoing military engagement that is taking place in Tipo-Tipo, Basilan Island which started on April 9, 2016, 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 Philippine soldiers and 5 militants reported killed and more than 70 others injured in total. It was the largest single loss of life for the Army since the beginning of the year, and came just one day after the group had released an Italian hostage.[1][2][3]
