Facebook CEO Mark Zuckerberg discussed the social network's quarterly results a day after his testimony by video, seen here, before a congressional antitrust panel

Facebook reported Thursday that its quarterly profit had nearly doubled and users grew despite a boycott by advertisers and the pandemic-induced economic turmoil.

The leading social network said it made a profit of $5.2 billion on $18.7 billion in revenue in the recently ended quarter, as the number of people using the platform monthly rose to 2.7 billion.

"This was a strong quarter for us, especially compared to what we expected at the start," chief executive Mark Zuckerberg said.

Shares in the Silicon Valley-based technology giant were up six percent in after-market trades following release of the earnings figures.

The number of people using the tech giant's overall "family" of apps including WhatsApp and Messenger each month topped three billion, according to Zuckerberg.

Zuckerberg said he could not predict when Facebook employees would return their offices, in light of surge in coronavirus cases.

"It is incredibly disappointing because it seems like the US could have avoided this current surge in cases if our government had handled this better," Zuckerberg said.

Facebook expected as much as half of its employees to be working from home on a long-term basis in the next five to ten years.

Organizers of a Facebook ad boycott have vowed to continue their campaign, saying the social network's top executives have failed to offer meaningful action on curbing .

The boycott aimed at pressing Facebook to act on toxic and hateful content has the support of more than 900 companies and organizations.

Zuckerberg said he was "troubled" by calls for regulators to make it more difficult to target advertising, saying such a move would hurt businesses trying to connect with customers, especially during .

"This would reduce opportunities for small businesses so much that would probably be felt at a macroeconomic level," Zuckerberg said.
