Pakistani social media campaigner Hanzala Tayyab leads about 300 ultranationalist cyberwarriors fighting an internet war with archfoe India in a battle that is increasingly sucking in global tech giants.

Tayyab, 24, spends his days on Facebook and encrypted WhatsApp chat rooms organizing members of his Pakistan Cyber Force group to promote anti-India content and make it go viral, including on Twitter, where he has more than 50,000 followers.

That ranges from highlighting alleged Indian rights abuses to lionizing insurgents battling Indian security forces in Kashmir, a disputed region at the heart of historic tensions between Pakistan and India.
