Local media reported at least 15 people, including 7 soldiers, have been killed and 75 others were injured in two explosions that rocked Sulu province on August 24.
Jolo has been sealed off to prevent the risk of similar attacks. Philippine officials have launched investigations to hunt for the culprit.
Sulu is known as the stronghold of the Abu Sayyaf Group, an armed group that has allied itself with ISIL.
Prime Minister Nguyen Xuan Phuc on August 25 sent a message of condolence to Philippine President Rodrigo Roa Duterte over the twin terrorist bombings in Jolo.
The same day, Deputy Prime Minister and Minister of Foreign Affairs Pham Binh Minh also offered his condolences to Philippine Secretary of Foreign Affairs Teodoro Lopez Locsin.
