Los Angeles: Kobe Bryant, one of the NBA's all-time greats whose international stardom transcended basketball, was killed on Sunday in a helicopter crash near Los Angeles along with his 13-year-old daughter and seven others on board.

A helicopter crash in the hills near Calabasas was also confirmed by the Los Angeles Times.

The incident came only hours after the former Los Angeles Lakers star, 41, was passed by current Lakers star LeBron James for third on the all-time NBA scoring list in a Saturday game at Philadelphia.

He was 41.

Bryant rocketed to fame as an 18-year-old rookie and played 20 years for the Los Angeles Lakers, 18 of them as an all-star, and winning five NBA championships. His death sent shockwaves through the National Basketball Association, which he helped propel to international prominence, and around the world.

The cause of the crash was unknown, and an investigation by the Federal Aviation Administration and the National Transportation Safety Board could take months.

Bryant was known to travel frequently by helicopter to avoid Los Angeles' infamous traffic, dating to his playing days.

His Sikorsky S-76 chopper went down in foggy weather around 10am (1800 GMT) in hilly terrain in Calabasas, California, about 40 miles (65 km) northwest of central Los Angeles, sparking a brush fire, officials said.

"There were no survivors. We have a manifest that indicates there were nine people on board the aircraft, the pilot plus eight individuals," Los Angeles County Sheriff Alex Villanueva told a news conference, declining to identify any victims.

Asked by reporters if he believed there were nine bodies at the crash site, after earlier reports indicated only five dead, Villanueva said: "That is our belief, yes.

"NBA Commissioner Adam Silver confirmed Bryant and his daughter Gianna were among those killed, and sent condolences to Bryant's wife, Vanessa.

"He was one of the most extraordinary players in the history of our game with accomplishments that are legendary," Silver said, as tributes poured in from players, politicians and entertainers.

Among the others on board, in addition to the pilot, were a teammate from Bryant's daughter's basketball team and a parent of the teammate, NBC News reported.

Orange Coast College baseball coach John Altobelli was also one of the victims, the Orange County Register reported, citing assistant coach Ron La Ruffa.

'Kobe we love you'

Reaction to Bryant's death was swift, and moments of silence were observed before some of Sunday's NBA games.

In San Antonio, the Toronto Raptors and San Antonio Spurs allowed the 24-second shot clock to expire on each of their first possessions, in tribute to Bryant's jersey number 24.

"I am in shock over the tragic news of Kobe's and Gianna's passing. Words can't describe the pain I'm feeling," said Michael Jordan, who won six NBA championships with the Chicago Bulls.

"Kobe was an amazing dad who loved his family deeply - and took great pride in his daughter's love for the game of basketball," Jordan said.

Stunned fans gathered near the Lakers' home arena - the Staples Center in downtown Los Angeles - surrounding a wreath with a message: "Kobe we love you RIP.

"Some in the crowd dabbed tears as others laid flowers and basketball sneakers at the wreath. Fans wore both his No. 24 and No. 8 jerseys, breaking the sombre mood with occasional chants of "Kobe, Kobe.

"Among those internationally recognized athletes known simply by their first names, Bryant was an avid supporter of soccer and women's basketball and spoke Italian, having spent part of his youth in Italy, where his father, former NBA player Joe "Jellybean" Bryant, played several seasons professionally.

He also won an Oscar, along with Glen Keane, for the 2017 animated short film "Dear Basketball," and sometimes mingled with show-business stars in Los Angeles.

'Much more than an athlete'

"Most people will remember Kobe as the magnificent athlete who inspired a whole generation of basketball players. But I will always remember him as a man who was much more than an athlete," Kareem Abdul-Jabbar, the all-time NBA scoring leader and former Laker, said on Twitter.

Bryant was accused of sexual assault in 2003 by an employee at a Colorado hotel, tarnishing his reputation and leading to a media storm to cover his trial.

Bryant denied the allegations and charges eventually were dropped after the woman refused to testify.

Bryant and his wife filed for divorce in 2011 after 10 years of marriage, but the couple said in 2013 they had reconciled.

Besides Gianna, they had three other daughters: Natalia, Bianca and Capri, who was born in June 2019.

Bryant played all 20 of his NBA seasons with the Lakers, winning five championships and being named an all-star 18 times. He also won two Olympic gold medals as a member of the US men's basketball team in 2008 and 2012.

Nicknamed "The Black Mamba," he became eligible to enter the Hall of Fame this year and is certain to be selected when the 2020 class is enshrined.

Bryant demonstrated from an early age he would surpass the accomplishments of his father, who played eight seasons in the NBA.

The Philadelphia native went straight from high school to the NBA, skipping the college ranks. Since he was still only 17 years old, his parents needed to co-sign his first contract with the Lakers and he played his first game with the team shortly after turning 18 in 1996.

He was the third-leading scorer in league history with 33,643 points, until LeBron James passed him on Saturday. In his final tweet, Bryant saluted James' achievement, writing: "Continuing to move the game forward @KingJames. Much respect my brother."
