World leaders condemn 'terror' attack in Paris
US President Donald Trump is condemning the latest "terror" attack to rock France, as political candidates for the nation's election speak out over the incident.
Appearing in a press conference with the Italian Prime Minister, Trump said it looked like a terror attack.
"Our condolences from our country to the people of France ... I just saw it as I was walking in, so that's a terrible thing," he said.
"What can you say? Just never ends.
"We have to be strong and we have to be vigilant," Trump added.
France's President Francois Hollande said he is convinced the attack is a terrorist act.
France is days away from its election, and the candidates looking to replace Hollande quickly posted on social media about the attack.

Marine Le Pen, French presidential candidate and president of France's National Front political party, said: "Emotion and solidarity for our security forces, again being targeted. MLP".
Fellow presidential candidate Emmanuel Macron pledged support for French police as well.
"Tonight, I want to show all my solidarity with our law enforcement," he said on Twitter.
Australian Prime Minister Malcolm Turnbull says Australia's prayers are with the family of the police officer shot dead on Paris' Champs Elysees.
He said the shooting had all of the hallmarks of a terror attack.
"But at this stage I'm advised that the French prosecutor is on the scene and they'll obviously be making further announcements as they investigate the crime," he told the Seven Network on Friday.
