The city of Los Angeles has paid tribute to basketball star Kobe Bryant with vigils and tributes after his shock death in a helicopter crash.

The 41-year-old died alongside his 13-year-old daughter, Gianna, and seven other people in the accident in Southern California on Sunday morning.

"This first picture were messages from THIS MORNING," O'Neal posted.

"I wish I didn't sleep in so I could've talked to you ... I can't even think straight right now.

"I love you man ... thank you for everything you've done ... for this city, for the basketball world, and for me ... I won't let you down ... you always counted on me and lifted me up."
