The heartbroken families of the Dunblane massacre have revealed how they have sent letters of support to Parkland students on the anniversary of the 1996 shooting.
Pupils at Marjory Stoneman Douglas High School in Parkland, Florida, have been protesting for tougher gun-control laws, after 17 people were killed in a mass shooting last month.
Today, on the 22nd anniversary of Britain's worst deadliest firearms atrocity, families of the Dunblane Primary School tragedy have told American protesters that they are standing with them over their call for change.
The massacre at the Scottish school, which killed 16 children and a teacher and also injured 15 others, sparked shocked the nation and led to the UK enforcing some of the strictest firearms legislation in the world.
The younger siblings of five-year-old victims, Joanna Ross and Emma Crozier appeared on Lorraine to reveal the letter they sent to the Parkland students in solidarity.
Jack Crozier told the ITV show: 'It's just all about a message of hope. This day is very difficult for everyone from Dunblane and it is a day of remembrance - and it's sending a message out to them that change can happen.
'It didn't all come straight away for Dunblane. For families of Dunblane it took a year for that first small step.
'It was high calibre guns that were banned first and it took another full year after that - the second anniversary - when all handguns were banned.
'It's not going to happen straight away. You're going to have these setbacks where promises will be broken but it's all about just keeping that fight up.'
Parkland students have held rallies, confronted elected officials and are promising to mobilise eligible youths to register to vote, all in an effort to push lawmakers for tougher gun-control laws.
A national demonstration is planned tomorrow, when organisers have called for a 17-minute school walkout in memory of those who died last month.
The Dunblane families' letter states: 'We persuaded British lawmakers not to be swayed by the vested interests of the gun lobby, we asked them to put public safety first and to heed what the majority of the British people wanted. Most politicians listened and acted.
'Laws were changed, handguns were banned and the level of gun violence in Britain is now one of the lowest in the world. There have been no more school shootings.
'We want you to know that change can happen. It won't be easy, but continue to remind everyone of exactly what happened at your school and of the devastation caused by just one person with one legally-owned gun. Never let anyone forget.'
Alison Ross, the sister of Dunblane victim, Joanna, said she is grateful that her son William, four, is able to go to school in a safe environment.
She said: 'I'm not an anxious mother. I'm very grateful that I'm able to send William to school without any gun threats. Our schools now are safe - I'm very grateful because it was our parents who did that.
'If our parents hadn't fought for that I wouldn't think anyone would blame me for not sending my kids to school. A lot of us think it couldn't happen twice but there is families in America that it has happened twice to.
'They shouldn't have to live like that. It's just a luxury that they don't have. It must be so terrifying for them.'
The pair revealed that they will be marching at the US Consulate in Edinburgh on March 24 - the same day 500,000 people are expecting to protest in Washington for stricter gun laws.
Ms Ross said, although her family were already close to the Croziers before the Dunblane massacre, the incident brought the community together and believes the power of united families will make the Parkland protesters' case stronger.
She said: 'We are very lucky that we were friends before. Our families are connected.
'Joanna and Emma were both christened together, started their first day of school together, went to Sunday school together. Their funeral service was together as well.
'A lot of the families are only connected because of what happened in Dunblane. Whereas we were connected before that.
'It's something we take for granted that we are able to go to school and be safe. For them (Americans) standing up - it's a totally different message from them and it's very powerful.
'I think because they are standing up for themselves - they just don't want to be victims. They just want to feel safe. And they are right - why shouldn't they be.'
Disgraced former Scout leader Thomas Hamilton was 43 when he carried out the planned execution of innocents, first cutting Dunblane Primary School's telephone wires before making his way to the gym hall armed with four legally-held handguns and hundreds of rounds of ammunition.
Inside the gym, 28 primary one pupils were preparing for PE class as he entered and began shooting, killing 16 children and their teacher Gwen Mayor and injuring 15 others.
The massacre on March 13, 1996, shortly after 9.30am in the Stirlingshire town shocked the nation and led to the UK enforcing some of the strictest firearms legislation in the world.
The shootings in the US have sparked a public outcry, with students meeting President Donald Trump and organising marches demanding tighter gun controls.
In a Facebook video, the Dunblane survivors and relatives say: 'We want you to know that change can happen. It won't be easy, but continue to remind everybody of what happened at your school and the devastation caused by just one person and just one legally-owned gun.
'Never let anyone forget. There will be attempts to to divide you, to deflect you and doubtless to intimidate you, but you've already shown great wisdom and strength.
'We wish you more of that wisdom and strength for this toughest of tasks, one that will be so important in order to spare your fellow Americans having to suffer the way you have.
'Wherever you march, whenever you protest, however you campaign for a more sensible approach to gun ownership, we will be there with you in spirit.'
They also offer their 'total support' for the March for Our Lives gun-control rally on March 24 in the US.
Those in Dunblane say they will light 17 candles on Tuesday evening to remember those who lost their lives in the 1996 massacre, and will also think of those who died in Parkland.
Dunblane families' letter to Parkland students
Dear Students of Marjory Stoneman Douglas School,On the most poignant day of the year for us we wanted to reach out and offer our deepest and most heartfelt sympathy to you and your teachers and to all the families and friends of those who died at your school on 14th February. We have watched and listened with tremendous admiration as you have spoken out for what you believe should happen now, a significant change of attitude towards the availability of guns in your country.Twenty-two years ago today our own lives were devastated when a gunman walked into Dunblane Primary School in Scotland and shot dead sixteen 5- and 6-year-old children and their teacher and injured many more. The children who were killed or badly injured were our daughters and sons, our grandchildren, our sisters and brothers, our nieces and nephews, our cousins. The teacher was our wife, our sister, our mother. Five of us are survivors. The gunman owned his four handguns legally, and we knew it had been too easy for him to arm himself with lethal weapons. Like you we vowed to do something about it. We persuaded British lawmakers not to be swayed by the vested interests of the gun lobby, we asked them to put public safety first and to heed what the majority of the British people wanted. Most politicians listened and acted. Laws were changed, handguns were banned and the level of gun violence in Britain is now one of the lowest in the world. There have been no more school shootings.We want you to know that change can happen. It won't be easy, but continue to remind everyone of exactly what happened at your school and of the devastation caused by just one person with one legally-owned gun. Never let anyone forget. There will be attempts to deflect you, to divide you and doubtless to intimidate you, but you've already shown great wisdom and strength. We wish you more of that wisdom and strength for this toughest of tasks, one that will be so important in order to spare more of your fellow Americans from having to suffer the way you have. Wherever you march, whenever you protest, however you campaign for a more sensible approach to gun ownership we will be there with you in spirit.Tonight we will be lighting 17 candles for those who died in Dunblane and will be remembering the 17 who lost their lives in Parkland. Our thoughts will also be with every other victim of gun violence.We offer you our total support for the March for Our Lives and sincerely hope you achieve success. It can be done. #NeverAgain.Matt Birnie, Bev Birnie, Steve Birnie, Lauren Birnie — Survivor and his familyAlison Crozier, John Crozier, Ellie Crozier, Jack Crozier, Fiona Buchanan, Allan Pollock, Allana Pollock, Morag Pollock, Olivia Pollock, Sophie Pollock – Family of Emma CrozierBarbara Dunn, Martyn Dunn, Alex Dunn — Family of Charlotte DunnEileen Harrild — SurvivorAllison Irvine, Ian Irvine, Bethany Irvine, Rachael Irvine, Scott Irvine, Andrea Linden, Amanda McNamara, James McNamara, Laurence McNamara, Nicholas McNamara, Katherine Robertshaw, Kevin Robertshaw, Mark Robertshaw — Family of Ross IrvineDuncan McLennan, Liz McLennan, Gregor McLennan, Rachel McLennan, Lauren Shaw — Family of Abigail McLennanRod Mayor, Joan Mayor, Debbie Mayor, Esther Proctor — Family of Gwen MayorJenny Morton — Sister of Emily MortonMick North, Nicola Cole, Gail Lockwood, Matthew Lockwood, Matthew North, Vanessa North, Christine Warren, Neil Warren, Peter Warren — Family of Sophie NorthAndrew O'Donnell, John O'Donnell, Sheila O'Donnell, Katie O'Donnell, Rhona McInnes, Anne Orr — Survivor and his familyEllen Petrie, Sandy Petrie — Parents of John PetrieKenny Ross, Pam Ross, Alison Ross, Andrew Ross, Carolyn Jones, Gareth Jones, Gavin Jones, Irene Smith — Family of Joanna RossAdam Savage, Elaine Savage, Gavin Savage, Kane Savage — Survivor and his familyDavid Scott, Karen Scott — Parents of Hannah ScottKareen Turner, Willie Turner, Duncan Turner — Family of Megan TurnerIsabel Wilson, Guy Wilson, Catherine Wilson — Family of Mhairi MacBeath
