Bosnian rescue workers have recovered the bodies of four miners killed when a gas explosion caused part of a mine to collapse, and were set to resume the search for a final body on Sunday.

Bosnia was hit by fresh protests against unemployment and corruption Saturday but the demonstrations were mostly peaceful as the country was left reeling from three days of rioting in the worst unrest since the 1992-1995 war.

Several hundred protesters again took to the streets of the capital Sarajevo and several towns across the country to vent their anger at the state of the economy in the Balkan nation where unemployment stands at 44 percent.
