The alert level for Indonesia's Anak Krakatau volcano has been raised to the second-highest level possible, after a series of eruptions, while all flights around the volcano have been rerouted and a 5km (three-mile) exclusion zone has also been imposed.
At least 220 people have been killed and 843 injured after a tsunami hit coastal towns on Indonesia's Sunda Strait government officials say. There was no warning of the giant waves which struck at Saturday night, destroying hundreds of buildings, sweeping away cars and uprooting trees.
