Abu Sayyaf, a jihadist terrorist group based in Sulu in the southwestern Philippines, claims to have kidnapped a 70-year-old German man and killed his female companion.

The kidnapping, if confirmed, would be the latest in a wave of sea-borne attacks perpetrated by Abu Sayyaf despite combined efforts of the Philippines, Malaysia and Indonesia to shore up maritime security — and despite President Rodrigo Duterte’s ramped-up military offensive against the group, according to the Associated Press.

During a phone call with the Philippine Daily Inquirer on Sunday, Muammar Askali, a spokesman for Abu Sayyaf, said that the group had captured the two tourists from a yacht. “Unfortunately, the other one died,” Askali said, referring to the woman. “She tried to shoot us, so we shot her.”

Askali reportedly allowed his captive, Juegen Kantner, to talk with Inquirer journalists, “Pirates took our boat and they took us. We [asked] the [German] embassy to help us,” Kantner said.

According to police reports they were abducted close to Pegasus Reef, around 40 nautical miles away from Taganak Island in Tawi-Tawi.
