Manila: Canadian hostage John Ridsdel, a former mining executive, has been executed by Abu Sayyaf militants in the Philippines, a Canadian government official confirmed on Monday.
Prime Minister Justin Trudeau will give a statement about Ridsdel`s execution at 12 p.m. MT (1800 GMT), on the sidelines of a cabinet retreat in Alberta, a spokeswoman told reporters.
The Philippine army said a severed head was found on a remote island on Monday, five hours after the expiry of a ransom deadline set by Islamist militants who had threatened to execute one of four captives.
The army would not immediately confirm whether the head was that of one of four people for whom the al Qaeda-linked Abu Sayyaf had demanded a ransom.
They are two Canadian men, including Ridsdel, along with one Norwegian man and a Filipino woman, who had appealed in a video for their families and governments to secure their release.
Residents found the head in the centre of Jolo town. An army spokesman said two men on a motorcycle were seen dropping a plastic bag containing the severed head.
The spokesman said Abu Sayyaf militants had threatened to behead one of four captives on Monday if the 300 million pesos ($6.4 million) ransom for each of them was not paid by 3 p.m. local time.
The initial demand was one billion pesos each for the detainees, who were taken hostage at an upscale resort on Samal Island on Sept. 21.
Abu Sayyaf is a small but brutal militant group known for beheading, kidnapping, bombing and extortion in the south of the mainly Catholic country.
It decapitated a hostage from Malaysia in November last year on the same day that country`s prime minister arrived in Manila for an international summit. Philippine President Benigno Aquino ordered troops to intensify action against the militants.
Security is precarious in the southern Philippines, despite a 2014 peace pact between the government and the largest Muslim rebel group that ended 45 years of conflict.
Abu Sayyaf is also holding other foreigners, including one from the Netherlands, one from Japan, four Malaysians and 14 Indonesian tugboat crew.
