French star DJ David Guetta was quick to share his solidarity with the victims of the Nice attack, in which at least 80 people were killed when a truck plowed into a crowd watching a fireworks display on what was France's national holiday.

Popstar Rihanna was in a hotel near the scene in Nice when the attack occurred. She was scheduled to perform Friday in the southern French city, but the concert was cancelled, along with the Nice Jazz Festival, set to begin Saturday.

Here, DW's Elizabeth Shoo sums up some blue, white and red images being tweeted and retweeted in solidarity.

But this time, a sentiment of anger, frustration and, most of all, futility, could be felt strongly on Twitter with posts like these:

The frequency of recent attacks weighed heavy on those posting reactions.

Jokes about trucks - which was the weapon used Thursday in Nice - having no religion and anti-immigrant sentiments were also rampant on Twitter.

Nevertheless, other users urged people to stay strong in their shows of support and not give up.

"Peace will win, fear will lose" was a popular slogan making its way through the internet early Friday morning.

And - in a play on the #jesuis meme and the name of the affected city - one French Canadian journalist kept it simple:
