A mob of wild monkeys went on a rampage in a village in eastern Indonesia, entering houses and attacking residents.
Seven people were injured, including one who is in a critical condition.
Ambo Ella, a spokesman for Sidendeng Rappang District in South Sulawesi province, said the surprise attack by about 10 monkeys happened in Toddang Pulu village.
He said a 16-year-old boy was badly bitten in the attack and is was being treated in hospital.
He believes the troop came from a nearby forest protected by a local tribe. It is unclear why the monkeys, which are usually afraid of humans and flee when they hear human voices, emerged and attacked.
Authorities are investigating to find out what prompted the attack, which caused panic among villagers.
