Paris counts down to start of 2015 attack trial

Security was tight on Wednesday as France prepared to open the biggest trial in the country's history over the Islamic State group’s 2015 attacks on Paris that left 130 people dead and hundreds injured. 

Nine gunmen and suicide bombers struck within minutes of each other at France's national soccer stadium, the Bataclan concert hall, and Paris restaurants and cafes on Nov. 13, 2015. 

The lone survivor of the extremist cell from that night, Salah Abdeslam, is the key defendant among those being tried for the deadliest attack in France since World War II. He is the only one charged with murder.  Twenty men are charged, but six of them will be tried in absentia.
