The athletics Diamond League meeting in Monaco will go ahead as scheduled on Friday despite the terrorist attack in nearby Nice.
At least 84 people, including several children, died after a man drove a truck through crowds celebrating Bastille Day along the Promenade des Anglais.
Monaco is 15 miles away along the Cote d'Azur, but the decision has been made for the meeting to proceed, although a number of changes have been made to the programme.
A statement from the event organisers said: "The Monegasque Athletics Federation, after concerting with its President, H.S.H. Prince Albert II, has taken the decision to uphold the Herculis meeting which will take place on Friday at the Stade Louis II in Monaco.
"This evening's programme will be kept strictly to the sporting events with no festivities.
"A tribute will be made to all the innocent victims of the Promenade des Anglais in Nice.
"The sporting community and the Principality of Monaco would like to express their solidarity and deepest condolences to all families and friends of the victims as well as to the national and regional French authorities."
There will be one minute's silence at the start of the televised section of the meeting, and athletes and officials will wear black ribbons as a mark of respect.
Twelve British athletes are set to compete in Monaco, including Mo Farah and London 2012 high jump bronze medallist Robbie Grabarz.
