Listen: 'Amazing people, lovely neighbours': Tribute to York victims of Manchester bombpublished at 07:16 British Summer Time 25 May 2017
A Polish couple who lived in York are now known to have been among the 22 who died in the blast.
Martin and Angelika Klis were at the arena to pick up their two daughters following the concert.
Jola Wrjton knew the couple very well.
She told BBC Radio York how she felt when she heard the news:
A minute's silence will be held across the UK at 11:00 to remember those who died in the attack, the dozens injured and all those affected.
