A volcano on a tiny Indonesian island is spewing out more hot ash and lava after causing six deaths over the weekend.

Hot lava from an erupting volcano killed six people sleeping in a beach village on a small island in eastern Indonesia on Saturday, after ash and smoke from the volcano shot about a mile into the air, officials said.

The six people swept up and killed by hot lava from an erupting volcano in eastern Indonesia had refused to leave the area for safer ground when the mountain began rumbling last year, an official said.
