Flags are being flown at half-mast across the region as a mark of respect for those who died at Manchester Arena.
Norfolk County Council, Suffolk County Council, Norwich City Council, West Norfolk Council, Broadland District Council, Attleborough Town Council and Great Yarmouth Borough Council are among local authorities which have lowered their flags in tribute to the victims.
A tweet from County Hall stated: 'We're flying the Union Flag at half mast today in honour of the victims of the Manchester terror attack #StandTogether'.
At Broadland, leader Andrew Proctor called for a minute's silence ahead of a meeting of the council's cabinet, while in Norwich, the mayor-making ceremony this afternoon will also be preceded with a minute's silence.
The Norfolk Constabulary and Norfolk Fire and Rescue Service flags were also flown at half-mast in respect to those affected by the attack.
