Kate and William continued their message: “Thank you also to the first responders who, despite the most horrific scenes, showed compassion and professionalism when your community needed you most. W & C.”

King Charles and Camilla Parker Bowles also expressed their condolences over the “utterly horrific incident”.

In a statement, King Charles said: “We send our most sincere condolences, prayers and deepest condolences to the families and loved ones of those who lost their lives so tragically, and to everyone affected by this truly abhorrent attack.”

The alarming scene took place during a dance and yoga workshop aimed at primary school children.

Merseyside police chief Serena Kennedy said authorities believe two adults were injured while “bravely” trying to protect the children.

Merseyside Police and Crime Commissioner Emily Spurrell said she was “utterly shocked and devastated” by the incident.

Spurrell said: “I cannot even imagine the untold pain and grief they are facing. My thoughts are also with everyone who has suffered injuries and who has been affected by this distressing incident.”

The commissioner added that an attack on “innocent, defenseless children” at the dance school was “unthinkable and absolutely abhorrent”.

“These young people had their whole lives ahead of them and it is difficult to find the words to convey our deep sadness. Our region will be heartbroken as more young lives have been lost to the violence and more people have been seriously injured, and I share the deep concern and fear of local people.”
