ISTANBUL: A forensic report into the deaths of four members of a Turkish-German family on holiday in Istanbul revealed they were likely exposed to chemicals, local media reported on Wednesday.

The family, who traveled from Germany to Turkiye’s largest city for a vacation, fell ill last week after eating several popular street food dishes in the waterside neighborhood of Ortakoy, at the foot of a bridge spanning the Bosphorus.

Turkish prosecutors launched an investigation, initially focusing on suspected food poisoning.

Eleven people have been detained in connection with the incident.

But a forensic report based on samples taken from the mother and the two children showed that their death due to food poisoning was a “lower possibility,” the daily Cumhuriyet said, citing the report.
