Hong Kong remains a safe city, Secretary for Security Ambrose Lee says responding to Thursday's terrorist attacks in Istanbul.

Mr Lee said there are no reports so far of Hong Kong people being involved in the bomb blasts.

He said the Government is highly concerned about the incident, and assessments showed that Hong Kong is an unlikely terrorist target. However, Police will maintain a high level of vigilance and state of operational readiness.

Close liaison with overseas law enforcement and intelligence agencies will be kept. It will also regularly review its security arrangements, particularly at the airport and on public transport systems, to ensure safety.
