UPDATE: 11:49 p.m. EDT — It was not immediately clear where the blame lies for the Philippines bombing late Friday night local time that killed at least 14 people and injured dozens more in Davao City. A terrorist group affiliated with the Islamic State group has claimed responsibility for it, according to multiple reports.

One Philippines news outlet reported that Abu Sayyaf, an apparent Southeast Asian faction of the global terror group more commonly known as ISIS, admitted to carrying out the deadly bombing at Roxas Night Market.

However, hours later a local journalist tweeted that Abu Sayyaf in Sulu province of the Philippines pointed the finger at Daulatul Islam, a different extremist group operating in the same region that is the reported byproduct of a "merger" between two separate militant groups in the country, Bangladesh news outlet the Dhaka Tribune reported last month.

While it was not immediately clear who the culprits were, the motive for the bombing seemed to elude local law enforcement, as well.

The entire nation was placed under heightened alert — a "state of lawlessness" that allows searches of vehicles at checkpoints — and Philippines President Rodrigo Duterte canceled a planned trip abroad in order to show attention to the tragedy that was still unfolding in his country, according to various social media reports from journalists covering the bombing as well as the president's official Twitter account.
