'This is for Syria', Paris attackers shouted

Paris: Terrorists who killed more than 150 people in a string of terror attacks shouted "This is for Syria" as they opened fire and exploded bombs, witnesses said.

Over 110 of the victims were massacred at a concert in the Bataclan theatre after terrorists burst in, opened fire and took hostages, forcing security forces to storm the venue.

France is a member of the US-led coalition combating the Islamic State.

An unnamed witness at the Bataclan rock concert where over 150 people were massacred by terrorists in a string of attacks in Paris on Friday night, recalled it as "war", BBC reported.

"It was a concert where the music was loud. I heard the shots, I turned around and I saw a silhouette with a cap who stood near the back door. He fired in my direction," BBC quoted the witness as saying.

"People began to drop and throw themselves to the ground. I thought that the guy next to me was dead."

The witness said he managed to exit from the venue.

"We hid in a cafe, barricaded on the first floor. When we told people what had happened they believed us immediately. It's war here, there were shots fired just a very short time ago.

"All we can hear are sirens, we are waiting to be evacuated...," the witness was quoted by BBC.
