News of the terrible events in Manchester broke last night, and immediately both the internet and the airwaves were filled with clamour and speculation.

Nineteen confirmed dead; at least 59 hospitalised; many children still being searched for by their parents. It is the stuff of nightmares, but, in this case, the nightmare is real.

We are told that the blast had all the elements of a terror attack, and the fact that the target was unarmed young people simply highlights the horror and revulsion we all feel.
