To target tourists at heavily travelled spot.

The Islamic State (ISIS) group claimed responsibility for the truck attack that killed 84 people in Nice on France's national holiday, a news service affiliated with the jihadists said Saturday.
Amaq quoted an ISIS security source as saying one of its "soldiers" carried out Thursday's carnage "in response to calls to target nations of coalition states that are fighting (ISIS)".
A statement from ISIS's official radio bulletin Al-Bayan said the attacker had carried out a "new, special operation using a truck".
Al-Bayan warned that Western countries "will not be spared from the blows of the mujahideen" no matter how much they increase their security measures.
