LONDON: Greta Thunberg has told Swedish officials she is being subjected to harsh treatment while in Israeli custody following her detention aboard a Gaza aid flotilla, according to a report in The Guardian.

In correspondence seen by the British newspaper and published on Saturday, the Swedish climate activist said she was being held in a cell “infested with bedbugs” and given too little food and water.

An email from the Swedish foreign ministry said embassy officials had been in contact with Greta, the report said.

“She has received insufficient amounts of both water and food,” it said.

“She also stated that she had developed rashes which she suspects were caused by bedbugs. She spoke of harsh treatment and said she had been sitting for long periods on hard surfaces.”
