President Francois Hollande called Saturday for national unity after the latest deadly attack in France, in which a Tunisian man ploughed a truck into a crowd in Nice killing 84 people, his spokesman said.

"We are in a time when, and we have seen it, there is a temptation to divide the country. Faced with these temptations, faced with this risk, we must recall the unity and cohesion of this country," said spokesman Stephane Le Foll, citing a message from Hollande to his ministers.

A gunman smashed a truck into a crowd of revelers celebrating Bastille Day in the French resort of Nice, killing at least 84 people in what President Francois Hollande on Friday declared a terrorist attack.
