From igloos to topless protesters, the World Economic Forum this year had its fair share of innovative protests and campaigns reflecting people's growing frustration with the present economic system and rising inequalities.

Three topless Ukrainian protesters were detained on Saturday while trying to break into an invitation-only gathering of international CEOs and political leaders to call attention to the needs of the world's poor. Separately, demonstrators from the Occupy movement marched to the edge of the gathering.

"It will happen and the pause cannot be too long," he said at a panel discussion on 'How Immune is India?' at the annual World Economic Forum meeting here.
