Hong Kong’s oldest zoo is seeking answers in a monkey medical mystery after nine animals died in two days, including three members of a critically endangered species.

Part of the Hong Kong Zoological and Botanical Gardens has been sealed off and disinfected, and experts have been called in to carry out necropsies and toxicological tests, Hong Kong leader John Lee said in his weekly press briefing on Tuesday.
