Danish shipowner Torben Ostergaard-Nielsen has received death threats over news reports linking his Dan-Bunkering to deliveries of jet fuel to Syria.
The tycoon, who also owns Uni-Tankers through his USTC Group, told local media he now has security personnel at his house.
"I have guards around my residence, I can't drive in my own cars, and I have to send text messages before I go anywhere," he told Avisen Denmark.
