Hong Kong Zoo Probes Mysterious Deaths of Nine Monkeys

Authorities investigate sudden fatalities at Hong Kong Zoological and Botanical Gardens, involving critically endangered species.

Nine monkeys, including critically endangered cotton-top tamarins, died at Hong Kong's oldest zoo over two days.
Experts have been called in to perform necropsies and toxicological tests to determine the cause of death.
Part of the zoo has been sealed off and disinfected; one De Brazza's monkey is under observation for unusual behavior.
Concerns have been raised about potential zoonotic diseases, with experts warning of pathogens transmissible to humans.
Hong Kong's government held an urgent interdepartmental meeting to address the situation and monitor other animals.
