At least 84 people, including two Americans, where killed and more that 200 others were injured Thursday night when a man plowed a truck into a crowd watching Bastille Day fireworks in the French Riviera city of Nice. Police shot and killed the driver. Here's the latest of what we know.

— U.S. TV news networks identified the Americans as Sean Copeland and his 11-year-old son Brodie from Lakeway, Texas, just outside Austin.

— French President François Hollande on Friday morning said the "terrorist character" of the  attack was undeniable, coming as it did on France's equivalent of the Fourth of July. Hollande said a state of emergency that has been in effect since the Paris attacks eight months ago, and which was set to expire, would be extended for another three months.

— François Molins, the prosecutor in charge of terrorism cases in France, said the death toll could rise. He said 202 people were wounded in the attack and that 52 of them were in critical condition.

—  The killer has been identified as Mohamed Lahouaiej Bouhlel, a 31-year-old truck driver who moved to France from Tunisia in 2005 and was a father of three children. He and his wife were divorced or in the process of getting a divorce.

— Hajer Khalfallah, a cousin of Bouhel's wife, told MailOnline Bouhlel was not religious. "He did not go to the mosque, he did not pray, he did not observe Ramadan. He drank alcohol, ate pork and took drugs. This is all forbidden under Islam. He was not a Muslim, he was a s---. He beat his wife, my cousin, he was a nasty piece of work."

—  No particular group has claimed responsibility yet, but Islamic jihadist groups praised the slaughter on social media.

—   Despite the attack, the 13th stage of the Tour de France was allowed to go ahead as planned under beefed up security. A moment of silence was held before the bicyclists took off.

— The path of death and destruction stretched for about 2 kilometers (1.3 miles) on the promenade on Nice's waterfront.
