M11 crash: 'Brother and sister' die in five-vehicle crash
Two people who died in a five-vehicle accident on the M11 in Essex are believed to be brother and sister, police said.
A man, 53, from the Netherlands and a woman, 45, from Kent died in the crash between Harlow and Bishop's Stortford at 14:15 BST on Thursday.
Two people travelling in another car were taken to Addenbrooke's Hospital.
A 49-year-old lorry driver arrested on suspicion of causing death by dangerous driving has been released on bail.
The crash on the northbound carriageway, between junction seven for Harlow and junction eight for Stansted Airport, involved three cars, a lorry and a horsebox.
Essex Police said the pair died at the scene when their Toyota car caught fire after being struck by other vehicles and colliding with the rear of a Mercedes horse box.
The 49-year-old driver of a Jaguar car from Romford who suffered head injuries is still in hospital along with his passenger, a 23-year-old woman from Cyprus, who was due to fly from Stansted Airport.
The lorry driver, from Stafford, along with the drivers of the horsebox and a Vauxhall van received minor injuries.
The road reopened at about 04:30 BST, the Highways Agency said.
The horsebox was carrying five animals from trainer Brian Meehan's stables.
A statement on the stable's website said the horses had been taken to the Newmarket Equine Centre, where they were being assessed.
