Some sort of irritant's been making people ill.
Around 600 pupils and staff have had to be evacuated from a school in Bournemouth this afternoon (Friday 14th October).
They've been sent home from Kings Park Primary School in Boscombe.
Dorset Fire Service say it's because of some sort of respiratory irritant but they don't know where it's come from.
Investigations are ongoing.
