Four Abu Sayyaf terrorists surrendered to the Philippine military in Basilan Province and three others gave in to the Philippine Marine corps on Sunday, according to CCTV reporter Huang Zhengzheng, citing Captain Jo-Ann Petinglay, Western Mindanao Command spokesperson.

"But the martial law declaration made them more fearful for their safety as soldiers can already knock at their doorstep without the necessary warrants," said Petinglay.

A total of 64 Abu Sayyaf terrorists have surrendered to Philippine government since January, according to Westmincom chief Lt. Gen. Carlito Galvez Jr.

At least 61 militants were killed by the Philippine army, according to Philippine military spokesperson Brig. Gen. Restituto Padilla.

President Duterte declared martial law for 60 days on the island of Mindanao on Tuesday after clashes between the army and militants with alleged link to ISIL in Marawi.
