U.S. Marine veterans are thought to be among seven motorcyclists killed following a devastating crash on a New Hampshire highway that left bodies strewn across the tarmac.

The tragic incident occurred on Route 2 near the town of Randolph shortly before 6.30pm Friday after a Dodge pick-up truck plowed into the procession of bikes.

Witnesses described a 'devastating' scene as bystanders tried to help riders that were peppered along the highway as emergency services rushed to help.

Along with the seven dead, state police said two additional people were transported to the Androscoggin Valley Hospital and one was airlifted to Maine Medical.

The crash involved members of Marine JarHeads MC, a motorcycle club in New England that includes Marines and their spouses.

'When something like this happens, we all feel it,' said Cat Wilson, who organizes a motorcycle charity event in Massachusetts and is a friend of some of the crash victims. 'There is no tighter community than our biker community.'

Authorities identified the pickup driver as Volodoymyr Zhukovskyy, 23, an employee of a Springfield, Massachusetts, company called Westfield Transport.

Zhukovskyy survived the accident and has not been charged, authorities said, but they didn’t release details on his condition or his whereabouts.

Police said they could not provide the identities of the dead until next of kin have been notified.

'It's tragic,' New Hampshire State Police Capt. Chris Vetter told reporters during a late news conference.

'It's tragic for those involved, tragic for the families, so we're doing our job, we're doing our work and our thoughts are with the people who were adversely affected by this.'

Parts of the rural two-lane highway was closed Friday evening, state police said, and would be closed for several more hours as investigators comb the scene for clues about what caused the crash.

A photo posted by WMUR-TV showed motorcycles and wreckage scattered across the highway and a truck on the shoulder in flames.

Meanwhile, fellow drivers quickly pulled over to try and assist in any way possible.

'Everybody got out of their car and helped, got blankets and first-aid kits. Everyone went into action and just helped,' eyewitness Miranda Thompson said to the network.

Meanwhile, another witness named Travis Hood said he tried to assist an injured man until authorities arrived.

'I held his hand, and I tried to get him to, I'm like: 'Squeeze my hand. Stay with me. You're a strong guy. You've got this. Toward the end, when the ambulance got there, I could feel him losing strength'.

Randolph is about a two-hour drive north of Concord, the capital, and a three-hour drive from Boston.

'There was debris everywhere,' said Miranda Thompson, 21, of Manchester, who was several cars back and recalled seeing a truck in flames on the side of the highway and six motorcycles.

'People were in the grass. There were people putting tourniquets on people, trying to make sure they didn't move,' she said.

'You could tell people were lost who it happened too... It was a sad day for all of them.'

Jerry Hamanne, co-owner of a nearby bed-and-breakfast that was hosting one of the bikers in the group, said he and a doctor also staying at his inn went to the scene to help. Others tried to assist as best they could but some people were already dead.

'It was so devastating to see the bodies on the road,' Hamanne said. 'My God, I don't want to see something like this again.'

The crash happened about 500 feet from lodging where most of the motorcyclists were staying, Hamanne said.

Charlie St. Clair, executive director of Laconia Motorcycle Week Association, which host one of the state's biggest rallies in June, said he couldn't recall an accident of this magnitude involving bikers in the state.

He wasn't on the scene but said had been fielding calls about the accident much of the night. St. Clair said he heard the riders were mostly Marine veterans who belonged to the same motorcycle club.

'This is staggering and it's tragic beyond description,' St. Clair said. 'You have a bunch of people out for a ride enjoying one of the first nice days we had. To have this happen, it defies logic quite frankly.'
