Thanks Fernando. This link relates to the BBC West story. According to it the airport is now re-opening.

The BRS website departures board suggests that nothing has taken off since around 1800 but about eighteen a/c have landed since then. Some others not yet landed are showing delays and presumably are being either held at the departure airport or sent elsewhere.
Must be getting crowded on the aprons. The live East Apron website plan is showing eleven parked there, so presumably the remainder are squeezing onto the West Apron.
I bet the old terminal hasn't seen so many people since 2000.
