Spain's data protection watchdog ordered US Internet giant Google on Thursday to pay a 900,000-euro fine for "serious violations" of users' privacy.
The Spanish Data Protection Agency accused the popular search provider of "illegal processing of personal data" obtained from users of various services such as Google email accounts.
"Google unlawfully collects and processes personal information" of users, the agency said in a statement.
"The agency considers that Google seriously violates the right to the protection of personal data."
It also accused Google of keeping the data for longer than is legally justified and of making it difficult for users to query the use of their data.
The Spanish authority launched proceedings against Google in June. In September, France too said it would take action against the company, accusing it of breaching privacy norms.
Authorities in Germany, Italy, The Netherlands and Britain have also opened parallel procedures against Google.
Like other technology giants, Google has come under scrutiny following revelations by US whistleblower Edward Snowden of online eavesdropping by US and other intelligence agencies.
