Two German hostages held by Islamic extremists in the Philippines arrived safely at the German embassy in Manilla on Saturday after being released.
The rebels had demanded more than 4 million euros in ransom and that Germany stop supporting US-led air strikes in Syria. They had threatened to behead Okonek on Friday afternoon.
Their captors from the Abu Sayyaf group have claimed that a ransom was paid but German and Filipino authorities refused to confirm that. Germany would say only that a crisis negotiator had been sent to the Philippines.
