The family of two British women and a baby girl who died in a car crash in Iceland say the accident has come as a "horrifying shock".Rajshree and Khushboo Laturia, and 10-month-old Shreeprabha Laturia, died when the 4x4 they were in careered off a bridge.Shreeprabha was the daughter of Rajshree and her husband Shreeraj Laturia.Mr Laturia, his brother Supreme and two other children, aged seven and nine, are being treated in hospital for serious injuries.The family said the accident had come as a "horrifying shock for the entire family and friends".They added in a statement: "The Indian, British and Icelandic authorities have been extremely cooperative and extended appropriate support."Special thanks to the local authorities for airlifting and ensuring timely medical facilities were provided."They said they were "deeply saddened" and asked for privacy.Image:Emergency services at the scene of the crashThe country's prime minister, Katrin Jakobsdottir, claimed the crash could be connected to the financial crisis of 2008.Since then, she said, Iceland's transport system had "not been maintained properly".A third brother, Sarvesh Laturia, who is in India, said it was "my two brothers and their wives - they are British people".Speaking to the Times of India, he added: "They were on vacation in Iceland and their car met with an accident in which my two sister-in-laws passed away and my niece passed away."My two brothers are in a critical condition in hospital."The rented Toyota Land Cruiser the two families from east London were travelling in fell at least six metres (20ft) onto the rocky river bank below a bridge near Skeidararsandur - a vast sand plain in southern Iceland at about 9.30am on Thursday.Image:The single-lane bridge over Nupsvotn in IcelandThe crash site was described as "horrifying" by tour guide Adolf Erlingsson, who was among the first on the scene with two police officers.He told Sky News: "It was quite a horrific scene.

The car went off the bridge and just crashed down - I would guess five or six metres - and was really badly damaged."When I got there, there were four people out of the car - one of them deceased."Ms Jakobsdottir said it was a "terrible accident", adding: "It shows the need for better infrastructure reform."Our transportation system has not been maintained properly after the financial crisis and it is under a lot of stress due to the two million tourists that visit every year, excluding the local population of course."The first rescue helicopter pilot on the scene, Andri Johannesson, who flew two of the survivors to hospital, told Sky News that conditions at this time of year could be unpredictable."Sometimes you can experience no ice, but a few minutes later, ice, so people really have to drive slowly," he said.While the cause of the accident is still being investigated, police said the vehicle seemed "to have turned on the bridge with the result that it went on top of the railing of the bridge, to the right, following it for a short distance and then turned over off the rail and the bridge".Officers doubt the road was icy prior to the crash, but say humidity could have made the bridge slippery.Both families lived in the same street in Poplar.

One neighbour, who did not want to be named, said it was "absolutely terrible", adding: "They were lovely people, absolutely peerless people."A family friend, who said her daughter went to school with one of the Laturia children, described them as a "very lovely family".The crash happened just south of Skaftafell National Park, where tourists go for camping, hiking and sightseeing.The bridge over Nupsvotn was built in 1973 and is 420 metres in length.It is expected to be replaced in the next few years by a shorter bridge about 100 metres long, according to information from the Road Administration department.
