At least seven foreigners who have been infiltrated into the southern part of the country are reported to be training suicide bombers in the region.

According to local media and foreign media on July 24, seven foreign terrorists were working in Mindanao Island and neighboring areas in southern Philippines.

Abu Sayyaf, a member of the local Islamic group, and BIFF, the veteran Islamic Freedom Forces Command (BIFF), pledged allegiance to the extremist militant group IS and are teaching local members how to commit terrorist attacks, including suicide bombings.

Military authorities said they did not specify their nationality, but they are linked to IS in Iraq and Syria.

Military authorities have also confirmed that there are 42 other foreign militants in the Mindanao region.

Professor Romel Balaoi of the Philippines, a security analysis expert, said that "radicals from Arab countries, Pakistan and Bangladesh are working with Abu Sayyaf, and an Egyptian couple who is affiliated with IS is educating suicide bombers." .

"We have had three suicide bombings in the Philippines since last year," said Delfin Lorenzana, the director of the Philippine Defense Ministry.

A Indonesian couple recently confirmed the death of a Catholic cathedral suicide bomber who killed more than 120 people in Holocaust in southern Philippines this January.

IS has announced a video in June 2016 that declares Southern Philippines as Caliphate and urges followers in Southeast Asia to join the Abu Sayyaf in the Philippines.

In fact, it was revealed that a large number of people from other countries, including Indonesia and Malaysia, were involved in the rebellion, which occupied Mindanao city of Mindanao island in March 2017 and engaged in fighting with government troops for months.
