Violent unrest this week has disrupted daily life in New Caledonia. Cars have been torched, shops looted, and police stations attacked, leading to hundreds of arrests.
The riots began when protests against constitutional reforms turned violent and widened into demonstrations against inequality and the state of the economy.
