BBC report says, hundreds of people have fallen ill and a child has died of suspected food poisoning at a camp for displaced people near the Iraqi city of Mosul.
People were said to be vomiting and suffering dehydration after an iftar meal, to break the daily Ramadan fast.
The Hasansham U2 camp, between Mosul and Irbil, houses people displaced by an Iraqi offensive to capture Mosul from so-called Islamic State (IS).
IS fighters are currently under heavy siege in the west of the city.
The UN refugee agency, UNHCR, said in a statement that around 800 cases had been recorded, 200 of whom were taken to hospital.
Unconfirmed reports say a second person, a woman, has died.
The agency said it was "extremely concerned" by the events at the camp.
"Staff have been working closely overnight to co-ordinate the response with other agencies and the relevant authorities to ensure that those who have fallen ill were able to receive swift medical treatment and that the seriously sick were provided transport to nearby hospitals," the statement said.
Another report says, the food, containing beans, chicken and yoghurt, was prepared in a restaurant in Irbil and brought to the camp by a Qatari charity.
It quoted camp supervisor Rizgar Obed as saying that outside organisations had previously been banned from bringing in food, but the camp authorities had been forced "under great pressure" to change the regulations.
It was later learned that people are being treated in three hospitals in the area.
The restaurant owner has been arrested.
