According to an official statement from the Guardia Civil Police, the Jota brothers were traveling in a Lamborghini car, which was involved in a road traffic accident and left the road due to a tyre blowout while overtaking.
"It was in the early hours, 00:30 BST, in the municipality of Cernadilla in the province of Zamora.
"The car caught on fire and the two occupants were killed."
It will be recalled that Jota only got married two weeks ago, and was part of the Portuguese squad that won the Euro nation's league final against Spain last month.
