Nice attack

Ten of the dead were children. Some 202 people were injured; 52 are critical, of whom 25 are on life support.

Prosecutors said Lahouaiej-Bouhlel had driven the lorry 2km (1.2 miles) along the famous Promenade des Anglais and fired at police before being shot dead.

The attack happened as thousands in Nice marked Bastille Day on Thursday.

Other weapons found inside the lorry were replicas or fake.

What the prosecutor said

The prime minister said Britain stood "shoulder to shoulder" with France after a lorry drove into a crowd killing at least 84 and injuring 50.

Downing Street says a "small number" of Britons were injured in Nice.

The attack was of "an undeniable terrorist nature", French President Francois Hollande has said.

UK police forces are reviewing security at major events over the next week.

A truck barrelled down the famed Promenade des Anglais seafront, sending hundreds of terrified people fleeing and leaving bodies strewn in its wake in what has been described as the "worst catastrophe" in the French Riviera's modern history.

The driver then fired a pistol several times before being shot dead by police, authorities said.

The identity papers of a 31-year-old resident of Nice who was born in Tunisia were found inside.

The driver ploughed on for 2km on the Promenade des Anglais at about 23:00 local time, before being shot dead by police.

President Francois Hollande said the attack was of "an undeniable terrorist nature".

A state of emergency, in place since November's Paris attacks, has been extended by three months.

France had been on high alert since those attacks in which 130 people died and hundreds were wounded.

The president of the Nice region, Christian Estrosi, said the truck was loaded with weapons and grenades, and the driver had opened fire on the crowd.

"An individual drove a truck into the crowd. He was killed by police," said interior ministry spokesman Pierre-Henry Brandet.

A photograph showed the front of the truck riddled with bullet holes, and badly damaged with burst tyres.
