A winning ticket in California's record $1.5bn Powerball jackpot was sold in a Los Angeles suburb, lottery chiefs have said.
It could take several hours before officials know whether any winning tickets in the world's largest lottery prize were sold elsewhere.
Update: Three winning tickets were sold.

The winning numbers were 04, 08,19, 27 and 34 and the Powerball was 10.
One winning ticket was sold at a 7-Eleven in Chino Hills, said lottery spokesman Alex Traverso. The identity of the winner is not yet known.
The store and its surrounding strip mall immediately became a wildly popular gathering spot in the usually quiet Los Angeles County suburb.
Dozens of TV news crews and members of the public crowded the store.
The store where the winner bought the ticket will get a million-dollar bonus for selling it, Mr Traverso said.
Officials with the Multi-State Lottery Association, which runs the Powerball game, said they expected more than 85% of the possible number combinations would have been bought for the drawing.
The odds of winning were 1 in 292.2 million.
Winners have to pay 39.6% of the prize in national income taxes, in addition to any state taxes.
Estimated jackpot amounts, which are released daily, have been steadily rising since November 4, when the jackpot was reset at $40m.
Powerball tickets are sold in 44 states, as well as the District of Columbia, the US Virgin Islands and Puerto Rico.
But people in the six states that do not participate found ways to get their hands on tickets.
Some of the biggest Powerball sales have come from cities bordering states, according to the Multi-State Lottery Association.
The association oversees the Powerball Lottery, but management rotates annually among member states.
