More than $98,000 has been raised in less than 24 hours for the family of a “much-loved” seven-year-old boy killed in the Barcelona terror attack.

Sydney schoolboy Julian Cadman became separated from his mother in last Thursday’s terror attack on Las Ramblas that left 13 dead and at least 120 injured.

His Filipina mother, known as Jom, was badly injured in the rampage and remains in hospital.

A GoFundMe page, with a goal of $1 million, was created on Sunday with money from supporters rolling in minute-after-minute.

As of 10am, almost 1300 people had donated over $99,000 in the campaign’s first 20 hours.

Donor Aileen Mountifield posted: “I am so sad for this family. I cannot imagine the pain and grief they are going through right now.”

Established by Scott Bowman, described as a family friend, the page says: “Andrew, Jom and Julian are a normal Aussie family whose lives have been devastated by the recent tragedy in Barcelona.

“As you can imagine, there will be ongoing medical costs to get Jom back to full health.

“We are asking for any contribution for those that may wish to help. This will assist with additional medical and funeral costs for the family. We thank you greatly for any support you may offer.”

After his death, a family statement said: “Julian was a much-loved and adored member of our family. As he was enjoying the sights of Barcelona with his mother, Julian was sadly taken from us.

“He was so energetic, funny and cheeky, always bringing a smile to our faces. We are so blessed to have had him in our lives and will remember his smiles and hold his memory dear to our hearts.”
