The Summer 2016 Sulu and Basilan clashes were armed conflicts that took place in two battlefronts on the southern islands of Mindanao, Philippines from 21 June to 12 July.
Background
After Canadian hostage John Ridsdel had been beheaded by Abu Sayyaf group (ASG) in late April 2016, Canadian hostage Robert Hall was beheaded on June 13, 2016. ASG even demanded $13 million ransom for the release of two other hostages.
Philippine President Duterte warned ASG to stop kidnapping, saying he would eventually confront them.
On 17 June, about five thousand Philippine soldiers had been deployed to the target areas in Sulu to track down ASG.
