Facebook has been accused of interfering in India's electoral democracy.
The Congress party has called on Mark Zuckerberg, the tech giant's CEO, to investigate claims that the company acted in a way that was favourable towards the ruling party.
KC Venugopal, Congress' general secretary, said: "This is a damning and serious allegation of Facebook India's interference in India's electoral democracy.
"As India's oldest political party that fought for the nation's freedom and established electoral democracy through adult franchise, it is deeply disturbing to note that your company may be a willing participant in thwarting the very rights and values that our founding leaders sacrificed their lives for."
Earlier this month, meanwhile, Facebook removed Donald Trump's "harmful" post in which he claimed that children are "almost immune" from coronavirus.
The US President said: "My view is that schools should be open
"If you look at children, children are almost - and I would almost say definitely - but almost immune from this disease."
The social media site deleted the clip for breaking its misinformation policy.
Facebook explained that the claim represented a "violation of our policies around harmful COVID misinformation".
