Narendra Modi and CEO both get emotional at event at Facebook headquarters in California, as pair discuss the role of internet and technology in India

The Indian prime minister Narendra Modi seemed at home at Facebook headquarters on Sunday, in a town hall event seen by many as an attempt by Facebook to gain much-needed support for its expansive ambitions in India.

Facebook CEO Mark Zuckerberg was certainly in a welcoming mood, changing his profile picture to include an Indian flag and writing: "I changed my profile picture to support Digital India, the Indian government's effort to connect rural communities to the internet and give people access to more services online."
