JAKARTA - Indonesia's Mount Lewotobi Laki-laki erupted at least three times early on Saturday, spewing an ash column 9 km high, as authorities planned to widen the restricted area, officials said.

A big eruption on Sunday by the volcano in East Nusa Tenggara province killed nine. Since then, authorities have been scrambling to evacuate 16,000 people from villages nearest the crater as eruptions continue.
