SINGAPORE - Singaporeans in Hong Kong should avoid the crowds and demonstrations in Hong Kong, the Ministry of Foreign Affairs (MFA) said in a travel notice on its website late Monday.

Warning that protests outside Hong Kong's government headquarters could spread to other parts of the city, MFA suggests that Singaporeans travelling to or residing in Hong Kong should " monitor the local news and developments closely and heed the instructions of local authorities."

It advises Singaporeans to e-register with the MFA to facilitate contact should the need arise, and also publishes emergency contact for those in need.

Singaporean travellers heading to Hong Kong, however, are undeterred, and tours and flights there are unaffected for now, reported the Strait Times on Tuesday.
