Opposition supporters in Guinea protested and erected barricades in the capital Conakry and the mining towns of Boke and Kamsar on Tuesday, disrupting some shipments of the aluminum ore bauxite, reports Reuters.

Quoting witness and industry officials Reuters said, the unrest sparked by a row over local elections held in February has paralysed much of Conakry since protests erupted on Monday.

Demonstrations spread to Boke on Tuesday, where police responded with teargas and clubs, a resident said.
