STN closed to arriving pax aircraft due mass disruption within the terminal due to a coach blaze earlier outside the terminal.
It appears passengers within the terminal at the time were quickly evacuated airside away from the fire & dense smoke for their own safety without obviously any security checks & now everyone airside are required to be rescreened even if they had been airside & already security checked!.
Arrival delay still undetermined & many diversions to LTN..LGW..EMA..&c.
Aircraft now being advised EMA..BHX..LTN all unable to accept diversions due volume of traffic.
