An attack whose origin remains uncertain has killed Sunday in the southern Philippines, said the authorities. The area remains unstable

One person was killed and 15 injured on Sunday in a bomb blast in a cybercafe in Isulan, southern Philippines, the second deadly attack in the city in a week, according to the authorities. Four of the 15 wounded are in critical condition, said the municipality of Isulan and the army.

The attack has not been claimed for the moment, but the authorities suspect the Bangsamoro Islamic Freedom Fighters (Biff), linked to the terrorist organization Islamic State (IS), to be at the origin. “The Biffs are responsible, this group is there to sow chaos,” said General Cirilito Sobejana. The explosion occurred not far from the previous one.
