Second Secretary (Press) Fakhrul Islam at the Bangladesh Embassy in Riyadh told bdnews24.com the fire devastated a residential building of expatriate workers in Holaifa area early Wednesday morning local time.
Two brothers - Jasim Uddin, 26, and Md Ibrahim, 23, - from Lakshmipur’s Kamalnagar are also among the casualties.
The other Bangladeshi killed in the fire is Mohiuddin Rashed, 35, from Feni’s Birinchi.
Labour Counsellor Sarwar Alam at the embassy said they were certain these six Bangladeshis died in the incident, but could not identify the bodies as those were badly charred.
He said DNA tests would be needed to identify the remains.
The injured Bangladeshi could not be identified immediately.
Selim said he heard the fire had originated from a carelessly thrown cigarette butt.
“They (seven victims) went to bed after having a meal on Tuesday night. Someone threw the cigarette butt in the veranda and an electric wire caught fire from it. The flames spread to the room,” he said.
