Indonesia flights rerouted as volcano alert level raised

All flights around Indonesia's Anak Krakatau volcano have been re-routed and the alert level has been raised to the second-highest possible after a series of eruptions spewed out lava. A five-kilometre exclusion zone around the volcano has also been imposed. On December 22, the volcano triggered a tsunami which hit the Sunda Strait coasts, killing over 400 hundred people.
