Around 1,000 animals were killed in a fire in Bangkok’s famous open-air Chatuchak market early Tuesday, gutting nearly 100 shops.

Birds, dogs, cats and snakes were burnt to death in their cages in the pet zone, which also included rats, pythons and geckos.

The blaze was started by an electrical short circuit, authorities said, adding that no human casualties or injuries have been reported.

The incident prompted renewed calls for authorities to shut the pet zone, which has long been criticised for the animals’ poor living conditions and has reportedly led to high rates of disease and death.
