Protests rage around the world – but what comes next?

Unrest is seemingly everywhere. We look at the some of the reasons for and responses to it in Hong Kong, Lebanon, Chile, Catalonia and Iraq

In Lebanon they are against a tax on WhatsApp and endemic corruption. In Chile, a hike in the metro fare and rampant inequality. In Hong Kong, an extradition bill and creeping authoritarianism. In Algeria, a fifth term for an ageing president and decades of military rule.

The protests raging today and in the past months on the streets of cities around the world have varying triggers. But the fuel is familiar: stagnating middle classes, stifled democracy and the bone-deep conviction that things can be different - even if the alternative is not always clear.
