FREETOWN, Sierra Leone (AP) — Volunteers going door to door during a three-day lockdown intended to combat Ebola in Sierra Leone say some residents are growing increasingly frustrated and complaining about food shortages.

Samuel Turay, 21, said Sunday that people in poorer neighborhoods of the capital, Freetown, were upset that handouts of rice and pepper were being distributed only to some houses.

Alexis Masciarelli, a spokesman for the World Food Program, said the agency had been providing food since the lockdown started Friday. But he said staffers were not going door to door and were instead relying on health care workers and volunteers to identify needy households.

Officials say Sierra Leoneans have largely complied with the lockdown designed to stem the biggest Ebola outbreak in history. The lockdown was set to end Sunday.
