Since 2016, normal Facebook users have been able to send disappearing messages using an encryption feature in Messenger, but they can not turn the tool on retroactively, and can not erase any sent messages older than 2016.
Facebook won't find "every single bad use of data, but what we can do is make it a lot harder for folks to do that going forward", he added.
The EU and Facebook will be looking at what changes the social media giant needs to make to better protect users and how the US company must adapt to new EU data protection rules. "These included limiting the retention period for Mark's messages in Messenger. We did so in full compliance with our legal obligations to preserve messages", the company said.
Van crashes into crowd in Germany killing two, injuring several
Police quickly evacuated the area and ambulances, firefighters and helicopters rushed to the scene to aid those who were injured. The German news agency dpa reports that police confirmed arrests in connection with the half-marathon but did not elaborate.
The report said that old messages from before 2014 still appear to some users, indicating the retraction did not apply to all chats the CEO sent.
Lawmakers had asked Facebook co-founder Mark Zuckerberg to explain to a parliamentary committee how the data got into Cambridge Analytica's hands. "Until this feature is ready, we will no longer be deleting any executives' messages".

"When we received word that this researcher gave the data to Cambridge Analytica, they assured us it was deleted", she said. A user can simply press down on the message they wish to eradicate and select "unsend;" the recipient will not be alerted if this happens. The tampering wasn't publicly announced; and the users weren't individually informed, either.
Reports suggest the data was then used by Cambridge Analytica as part of its work on Donald Trump's 2016 presidential campaign, though the British firm denies this.

Zuckerberg apologized after a backlash, calling it "a major breach of trust".
