I haven't heard or see anything about the r.o.i fans booing and whistling through the minutes silence
I heard it on 5 Live, lots of noise during minute silence, shouting etc others in crowd booing those shouting. Read suggestions Bosnians shouting, Irish booing them. Certainly wasn't obvious on radio who was doing what and certainly wasn't well observed.
Just seen a clip of it on youtube. Literally 2 of the 2,000 bosnian fans started shouting 'Palestina'. This provoked booing from the Irish end.It also provoked whistling from many of the Bosnian fans which in many European countries is a way of expressing dissaproval.
