Soldiers, police officers and firefighters walk near dead bodies covered with a blue sheets on the Promenade des Anglais seafront in the French Riviera town of Nice on July 15, 2016, after a truck drove into a crowd watching a fireworks display.
Four people have been in arrested in France in connection with a lorry attack that killed at least 84 people in the city of Nice, as the Islamic State of Iraq and the Levant (ISIL) claimed responsibility for the carnage on the country's main national holiday.
HH the Deputy Emir Sheikh Abdullah bin Hamad al-Thani and HE the Prime Minister and Minister of Interior Sheikh Abdullah bin Nasser bin Khalifa al-Thani have also sent cables of condolences and consolation to President Hollande on the victims of the terrorist attack, QNA said.
Hollande said France's state of emergency, set to end later this month, would be extended another three months.
One of the five people detained by police is Bouhlel's ex-wife, who was taken into custody Friday morning.
Mohamed Bouhlel, 31, drove a truck through a crowd yesterday killing 84 people.
Police shine a light as they approach the truck driver's cab late on Thursday. He had three children.
Suddenly, he slammed his foot on the gas, and screams pierced what moments earlier had been an evening of celebration and fireworks for France's national day.
He said the toll from the attack could rise. "I don't think he managed to turn his gun's safety off. That's when I said to myself, these people are jokers".
People attended mass on Friday to honour the victims of Thursday's attack.
The Queen added her voice to the wave of sympathy from leaders across the world as the country faced another terrorist attack, following those in Paris in November, in which 130 died, and in January 2015 in which 17 were killed.
In a tweet, Victorian Premier Daniel Andrews said "as we mourn tonight, we remember the values at the heart of the French tradition: liberty, equality, fraternity".
