A group claiming to be the Syrian Electronic Army hacked Twitter accounts run by Barcelona last night. The hackers used the accounts to send Barcelona a message related to their sponsorship by the Qatar Foundation.
They also sent out a greeting to Real Madrid.
The tweets were deleted shortly after.
It's not the first time a group claiming to be the Syrian Electronic Army have hacked a football related account. They hacked the accounts of Sepp Blatter and the FIFA World Cup last year.
