REPUBLIKA.CO.ID, MONROVIA -- Authorities imposed a curfew in a town in northern Liberia after violent protests following a wave of suspected ritual killings, authorities said on Wednesday.

Residents of Ganta on the border with Guinea said protests began after the killing of a motorcyclist on Wednesday. That came just a day after the discovery of the body of a 13-year-old girl who had disappeared weeks earlier.

A local police commander said one person was killed and several were wounded in the protests, in which several properties were destroyed. Government officials in Monrovia did not confirm the death.

"We will not hesitate to bring to book anyone in connection with this violence," Justice Minister Benedict Sannoh said in a national address. He said six people had been arrested for their part in the protests.
