French President Francois Hollande has canceled his trip to Prague planned for next week following the deadly attack in Nice.

The Czech presidential office says it was informed about the decision by the French embassy in Prague.

Hollande was expected to meet Czech leaders on Wednesday. The stop was part of a trip to five European countries meant to discuss the future of the European Union after Britain voted to leave the bloc.

An Islamic State-run media outlet says the man who barreled his truck into a crowd in the French coastal city of Nice is a "soldier" of the group.

The Aamaq news agency cited a "security source" as saying the attacker "carried out the operation in response to calls to target the citizens of coalition countries fighting the Islamic State."

The statement did not name the attacker, and the language implied that he may have acted independently. There is no evidence IS was involved in planning the July 14 attack.

The attack killed 84 people and wounded 200. The driver was identified as Mohamed Bouhlel, a Tunisian deliveryman known to authorities as a petty criminal.
