Prince William meets with Manchester bombing survivors, first responders

William, 34, also signed a condolence book at Manchester Cathedral.

William, the second in line to the British throne, signed a condolence book at Manchester Cathedral, writing "Manchester's strength and togetherness is an example to the world. My thoughts are with all those affected."

Among the victims were some of Grande's young fans and their parents who were waiting to pick their children up after the concert. The blast occurred in the venue's foyer, just after pink balloons were released from the arena's ceiling.

William later visited the Royal Manchester Children's Hospital to meet with young survivors of the attack and their families.

William, who is an air ambulance pilot, also visited emergency call handlers who spoke with victims and heard their desperate cries for help in the immediate aftermath of the bombing. He also spent time with representatives from St. John Ambulance, Northern Rail and the British Red Cross, all of which provided aid after the explosion.

The benefit, which sold out in just six minutes, is scheduled for Sunday at Old Trafford Cricket Ground, about 4 miles from the site of the May 22 attack.
