Nearly 1,000 pigs in Bali have died from an as-yet-unidentified disease, local authorities say. 

Pig farmers are concerned that the disease is related to the African swine fever (ASF) outbreak that has resulted in the deaths of almost 50,000 pigs in North Sumatra over the past few months, but Balinese officials have yet to confirm the suspicions, saying they are awaiting the results of laboratory tests.
