In short:
Spanish police are investigating whether speed was a factor in the single-vehicle crash that killed Liverpool striker Diogo Jota and his brother early on Thursday.
The men, who were both professional footballers, died when the Lamborghini they were in careered off a motorway near Spain's border with Portugal.
What's next?
Authorities say it could be several days before they finalise preliminary reports into the crash.
Authorities probing the death of Liverpool footballer Diogo Jota and his brother say they are trying to determine how fast the pair's car was travelling before it crashed this week.
Jota, 28, and his 26-year-old sibling André Silva were killed when their Lamborghini veered off a motorway in Spain's western Zamora region at about 12:30am on Thursday, local time.
A spokesperson for the Civil Guard law enforcement agency, which is leading the investigation, said it was “believed” one of the supercar's tyres had a “blowout” before the crash.
“At this moment in time it is impossible to say at exactly what speed the car was going but that is something the Civil Guard investigators will be able to detail at least approximately in their final report from things like the skid marks,” they said.

“What I can confirm is that no other vehicle was involved and no-one else was hurt.”
It is understood the car Jota and his brother were in was overtaking another vehicle at the time of the crash.
The crumpled, burnt-out wreck of the Lamborghini was removed from the site early on Thursday, but debris remained on the side of the road.
The UK's PA news agency on Thursday quoted a Spanish government source as saying investigators were treating the fatal smash as “a possible speeding incident”.

Ángel Blanco, a local government official, also gave a statement on Thursday, local time, in which he cited a burst tyre as being central to the crash.
Among those delivering tributes on Thursday were politicians in Spain and the UK, footballers and the British royal family.
Jota, a striker, was renowned globally for his exploits on the pitch.
He scored 47 goals in 123 matches for English Premier League giants Liverpool, where he played for the past five seasons. He also made 49 appearances for Portugal's national team.
His brother was also a professional footballer, turning out for Portuguese second-division club Penafiel.
