If I understand this correctly, there's to be a memorial service in the old Oslo cathedral at 11 today, with the entire royal family, the PM and his entire cabinet, the various party leaders, and whatnot.
TV2 here reports that in addition, anyone's invited, limited space providing.
Doors open at 9, there's been a sort of memorial mound of flowers, candles, etc. built up outside the cathedral overnight.
Extra security? Not very much.
Makes me proud to be Norwegian, if...
