"Of course, Mr Zuckerberg's apologies are not enough".

And he left many European lawmakers outraged after avoiding their questions on everything from data protection to fake news and election security.

"We do expect to be fully compliant on May 25", Zuckerberg said.

The meeting came two months after news surfaced Cambridge Analytica, a data firm connected to President Donald Trump's campaign, had access to information on up to 87 million Facebook users without their knowledge.

He added: "Whether it's fake news, foreign interference in elections or developers misusing people's information, we didn't take a broad enough view of our responsibilities". "That was a mistake and I am sorry for it", he said.

Zuckerberg addressed the question of "competition" in his remarks, saying that Facebook has to constantly compete to stay relevant.

Facebook CEO Mark Zuckerberg told a group of European Union officials Tuesday that the social network is working to prevent a repeat of the alleged Russian campaign to interfere with the U.S. presidential election in 2016.

Using the hearing's format to his advantage, Zuckerberg then chose which questions to answer and left after repeating the public statements he's been making since the Cambridge Analytica scandal broke in March.

While the European Parliament's powers are limited to scrutinising draft legislation, its members, along with the European Commission, the EU's executive agency, have used the recent scandal as a reminder of why tough new EU privacy rules kicking in at the end of next week are justified.

One unanswered question centered on whether Facebook cross-references data from its users and users of WhatsApp. The CEO agreed to follow up in writing to numerous questions and offered to send a company representative to testify before a future hearing.

"Will you allow users to escape targeting advertising?" "He responded to our offer of a meeting", he said.

The format of the meeting meant all MEPs asked their questions one after another, allowing Zuckerberg in the end to pick and choose which questions to answer before time ran out. "You asked for this format, well, for a reason". To which Zuckerberg responded with a slightly dismissive, "I'll make sure we follow up and get you answers".

Britain's Syed Kamall of the European Conservative Group asked Zuckerberg, "How can non-users stop Facebook collecting their data?" He also asked how Facebook commercializes that data.

"It seems to me, very near to reality", Verhofstadt said, noting that the fictional company's data was also used to affect elections.

Guy Verhofstadt, a Belgian MEP who leads the Alliance of Liberals and Democrats for Europe, reminded Mr. Zuckerberg that he has already apologized "15 or 16 times in the last decade" for Facebook's past missteps. He then moved on to equally pointed questions.

"Facebook, and Zuckerberg in particular, has been seen as uncooperative, even actively resistant towards European law and attitudes for a long time", said Paul Bernal, senior lecturer in IT and media law at the University of East Anglia.

Al Jazeera's Jonah Hull, reporting from Brussels, said that Zuckerberg provided "pretty un-enriching" responses to the MEPs' questions. They questioned the closed-nature of the Newsfeed algorithm, whether Facebook is a monopoly, and how it will comply with an upcoming new privacy regulation in Europe.

There was no mention of Diamond and Silk, aka Lynnette Hardaway and Rochelle Richardson, the pro-Trump personalities discussed in the USA hearings after becoming a cause célèbre among US conservatives who claimed the duo were being censored on Facebook.

Exactly how you could break up a social networking company is less clear.
