A National Public Radio report on a rebel insurrection in the West African nation of Sierra Leone deeply concerned Hanover-area listener Jim Ellenson Monday. 'Apparently, the Sankoh-led Revolutionary United Front rebels are rapidly advancing on Freetown,' said Ellenson, listening to NPR while leafing through the latest issue of The Nation. 'Hopefully, the U.N. peacekeepers will be able to limit the movement of the RUF in the interior near Masiaka.' Ellenson said he plans to stay tuned to NPR for the latest on the crisis.
