The Islamic State group claimed responsibility for both attacks via the jihadists’ propaganda outlet Amaq, which said they were carried out by its "soldiers". It did not provide any evidence for either claim and Las Vegas police said they had found no link between the gunman Stephen Paddock and the terrorist group.

"Tonight we will turn off the Eiffel Tower from midnight in homage to the victims of the attacks in Marseille and Las Vegas," Paris mayor Anne Hidalgo wrote, adding the hashtag "we are united".

The French capital has repeatedly switched off the night-time lights on its most famous landmark to show solidarity with victims of terror attacks from London to Kabul.
