Police say the incident was not a terror-related attack

The police are treating the case as non-terror-related, however, they are still to determine the motive behind the attack.

A witness called the scene "horrendous" and added that they had "never seen anything like it."

According to police, 13 ambulances and fire services were immediately rushed to the dance class which was organized for children aged between six and 10.

Chief constable Serena Kennedy, in her news conference, said that officers responding to the calls "were shocked" to find multiple people injured, most of the victims being children.

"It is understood that the children were attending a Taylor Swift event at a dance school when the offender armed with a knife walked into the premises and started to attack the children," she said.

Meanwhile, the police statement read, “The nine-year-old girl died in hospital in the early hours of this morning, Tuesday, July 30."

"We can confirm that the children who died yesterday were girls aged six and seven years. Eight other children suffered stab wounds sustained during the attack, and five of them are in a critical condition. Two adults are also in a critical condition after being injured during the incident,” it continued.

Merseyside Police Chief Constable Serena Kennedy said police understand the attacker walked into the premises carrying a knife and went on attacking children.

“We believe that the adults who were injured were bravely trying to protect the children who were being attacked,” she said at a news conference on Monday evening, July 29.
