An eight-storey apartment block has collapsed in the Turkish city of Istanbul, killing one person, while other people were injured or are trapped beneath rubble.

Video from a residential area in the city’s Kartal district shows rescuers at work around a mound of debris.

Reports suggest at least four people may be missing, and a number of cars were also buried in rubble.

The cause of the disaster on Wednesday afternoon was not immediately known.

A textile workshop on the building’s lower floor was empty at the time, local official Zeki Dag told local media.

According to CNN Turk, the building collapsed at about 16:00 local time (13:00 GMT).
