Two Hong Kong residents have been confirmed dead in the wake of last night's devastating bomb blast in the heart of the Thai capital Bangkok, Hong Kong's Immigration Department said Tuesday morning.

The two Hong Kong people who died were women aged 19 and 24. The department also confirmed six other Hong Kong residents injured in the incident and they have been sent to local hospitals for treatment.

Three Hong Kong immigration officers will fly to Bangkok this morning to provide help to the victims and their family members.

The Immigration Department advised residents already there to attend to personal safety and remain at safe areas.
