PARIS: Gunmen and bombers attacked restaurants, a concert hall and a sports stadium at locations across Paris on Friday, killing at least 120 people in a deadly rampage that a shaken President Francois Hollande called an unprecedented terrorist attack.

A Paris city hall official said four gunmen systematically slaughtered at least 87 young people attending a rock concert at the Bataclan music hall. Anti-terrorist commandos eventually launched an assault on the building. The gunmen detonated explosive belts and dozens of shocked survivors were rescued.

Some 40 more people were killed in five other attacks in the Paris region, the city hall official said, including an apparent double suicide bombing outside the national stadium, where Hollande and the German foreign minister were watching a friendly soccer international. Some 200 people were injured.

The coordinated assault came as France, a founder member of the U.S.-led coalition waging air strikes against Islamic State fighters in Syria and Iraq, was on high alert for terrorist attacks ahead of a global climate conference due to open later this month.

The deadliest attack was on the Bataclan, a popular concert venue where the Californian rock group Eagles of Death Metal was performing.
