Twitter said that an official Twitter account of the Olympics and the International Olympic Committee’s (IOC) had been hacked and temporarily locked.
The accounts hacked through a third-party platform, a Twitter spokesperson said in an emailed statement.
He did not give any further details.
“As soon as we were made aware of the issue, we locked the compromised accounts and are working closely with our partners to restore them,” the spokesperson said.
A spokesperson for the IOC separately said that the IOC was investigating the potential breach.
Twitter also said Spanish soccer club FC Barcelona’s account faced a similar incident on Saturday.
“FC Barcelona will conduct a cybersecurity audit.
It will review all protocols and links with third party tools, in order to avoid such incidents,” the soccer club said in a tweet.
Last month, the official Twitter accounts of several U.S. National Football League (NFL) teams.
The teams include San Francisco 49ers and Kansas City Chiefs, hacked a few days ahead of the Super Bowl.
Earlier this month, some of Facebook’s official accounts compromised briefly.
