Three people were in hospital on Friday morning after a fire broke out in a nine-storey tenement block in Hong Kong. Emergency services were called at 9.47am when a first-floor subdivided flat burst into flames in Kam Ning House, a 47-year-old block on Fuk Wing Street, Sham Shui Po. Nine fire engines and three ambulances were sent to the scene, according to the Fire Services Department. A spokeswoman for the department said 30 residents fled the building before firefighters arrived. She said firefighters used a water jet to battle the blaze, which was extinguished at 10.09am. The subdivided flat was severely damaged. “Three residents – two men aged 42 and 70 and a woman, 67 – complained of feeling unwell after inhaling smoke,” she said. The three were sent to hospital. A police spokesman said the fire was believed to have been caused by a short circuit in a fridge and an initial investigation found nothing suspicious.
