As many as 20 people might be missing.
BRASILIA, Brazil — A towering slab of rock broke from a cliff and toppled onto pleasure boaters drifting near a waterfall on a Brazilian lake Saturday and officials said at least six people died. Edgard Estevo, commander of the Minas Gerais State Fire Department, said at a news conference that in addition to the dead as many as 20 people might be missing and officials were seeking to identify them. Officials said at least 32 people were injured, though most had been released from hospitals by Saturday evening. Video images showed a gathering of small boats moving slowly near the sheer rock cliff on Furnas Lake when a fissure appeared in the rock and a huge piece toppled onto at least two of the vessels.
