France began a period of national mourning on Saturday for the 84 people killed when a Tunisian man smashed a 19-ton truck into a mass of people celebrating France's Bastille Day in the Riviera city of Nice. Some 30,000 people had thronged the Promenade Des Anglais to watch a fireworks display with their friends and families on a night which turned to horror as the rampaging truck left mangled bodies strewn across the palm-fringed road. President Francois Hollande said the country would observe three days of mourning as he warned the death toll could rise further, with more than 50 people still fighting for their lives. The massacre, which comes after two major terror attacks in France in 2015, has once again shaken the country to its core, raising questions over intelligence and security failings and how to stop such unsophisticated, yet deadly, assaults. Investigators were piecing together a profile of the driver, Mohamed Lahouaiej-Bouhlel, 31, a man with a record of petty crime, but no known connection to terrorist groups. Prime Minister Manuel Valls said the attacker probably had links to radical groups, but Interior Minister Bernard Cazeneuve cautioned it was too early to make the connection. In Nice, the seaside streets that would normally be bustling on a summer weekend were near-deserted, with teary residents making their way to the promenade to lay down flowers in memory of the dead. Photographs after the carnage showed the truck, which had been hired on Monday, with its front badly damaged and riddled with bullet holes. Molins said a fake pistol, fake rifles and a dummy grenade were found inside. One woman, Nataje, 52, said she heard a "boom" as the truck began accelerating into spectators on the Promenade des Anglais, the showpiece coastal road in the southern French city. "I turned round and I saw the truck which was crashing into the crowd and bodies flying into the air," the Nice resident said. "It was horrible. I saw a father with his two-year-old son in his arms. The child was dead." At least 10 children and teenagers were among the dead. Some 200 people were injured in the assault, among them around 50 children, with some "hanging between life and death," a hospital official said. "There are French among the victims and also many foreigners from every continent and many children, young children," Hollande said after visiting a hospital. Two US citizens, a Russian woman, a Ukrainian, two Swiss nationals and three Germans were among those killed. Hollande described the incident as a "terrorist attack" in a sombre televised address, adding that "France was struck on its national day... the symbol of freedom."
