RIO DE JANEIRO (Reuters) - Armed men shot at members of a convoy transporting uranium to one of Brazil's two working nuclear power plants on a coastal road in Rio de Janeiro state on Tuesday, police and the company managing the plant said.

They said the truck carrying the nuclear fuel and its police escort came under attack when it was passing by the town of Frade, about 30 km (19 miles) from Angra dos Reis, where the reactor is located.
