The Prime Minister wrote in his Facebook post: "I thank Mr. Mark Zuckerberg for the invite to visit the Facebook HQ. I look forward to the Townhall Q&A on Sunday 27th September at 10 PM IST (9:30 AM Pacific time). 

The interaction will cover a wide range of issues and will surely be a memorable one.

I urge you all to share your questions on the 'Narendra Modi Mobile App.' Your questions will make this a programme to be remembered."
