All four suffered serious injuries and were evacuated by rescue teams to Sultanah Nur Zahirah Hospital in Kuala Terengganu.
“However, three of the victims were pronounced dead on arrival at the hospital’s emergency department,” the source said.
The deceased were identified as Faezuan Hakim Bustaman, 28, Ahmad Fikri Zakaria, 38, and Nik Hafifi Asri Ab Majid, 37.
The injured man, Taufik Ruslan, 36, is receiving treatment at the hospital.
