A number of children attending a music festival were rushed to hospital due to an "extraordinary medical incident". Llangollen International Musical Eisteddfod, which takes place every year in Llangollen, north Wales , was cancelled on Wednesday following a "flu-like outbreak". Eight children fell ill and were taken to hospital, the Welsh Ambulance Service confirmed, and all of them were treated for mild respiratory symptoms. Public Health Wales said none of the children were seriously unwell.
