Paramedics battled for more than an hour to try to save one of the London Bridge terror attack victims, both of whom died from “shock and hemorrhage” after being stabbed in the chest, according to evidence presented during a hearing into the attack Wednesday.

Cambridge University graduates Jack Merritt, 25, and Saskia Jones, 23, were killed by convicted terrorist Usman Khan on Friday while trying to help him with a prison rehabilitation program, police told London’s top court, the Old Bailey, according to The Telegraph.

Khan, masquerading as a reformed jihadist, was eventually tackled by onlookers and finally shot dead by cops.

Armed officers had raced to the Fishmongers’ Hall on the banks of the bridge after “reports of a male attacking delegates” at just before 2 p.m., the opening of the inquest into the three deaths was told.

Merritt, who was the Learning Together course co-ordinator, was stretchered away by cops, and paramedics battled to save him for more than an hour, the inquest, which was headed by London’s chief coroner, heard.

He was finally pronounced dead at 3:14 p.m.

Jones, who was volunteering at the workshop event, was pronounced dead at 2:25 p.m. while still inside the hall, the report says.

The cause of death for both was recorded as “shock and hemorrhage” from being stabbed in the chest. Three others were injured.

Khan was described at the hearing as a “convicted terrorist” who was “restrained on London Bridge by several members of the public” after the attack.

“He was subsequently shot by police,” detective superintendent Desmond Hugh told the hearing, with Khan pronounced dead at 3:07 p.m. as paramedics still battled to save Merritt, the report said.

“Mr Kahn was examined by a pathologist who recorded a cause of death as shock and hemorrhage, and multiple gunshot wounds to the chest and abdomen,” Hugh said.
