Meta Platforms Inc's WhatsApp said on Thursday that it was working to keep users in Iran connected after the country restricted access to the app and social media platform Instagram, News.az reports citing Reuters.

WhatsApp "will do anything" within its technical capacity to keep the service accessible and that it was not blocking Iranian phone numbers, the messaging service said in a tweet. 

Iran on Wednesday restricted access to Instagram and WhatsApp, two of the last remaining social networks in the country, amid protests over the death of a woman in police custody, according to residents and internet watchdog NetBlocks.
