Bahrain's police fired tear gas and used sound bombs to disperse hundreds of demonstrators on Saturday in a Shiite village near the capital, witnesses said.
They said the incident took place at a road junction in Sanabis following the funeral of a 15-year-old youth.
He died earlier the same day in hospital of burns he had suffered during an attack Friday "by a group of saboteurs on a construction firm's warehouse," according to the interior ministry.
