Dozens of people quarantined for Ebola monitoring in western Liberia are reportedly threatening to break out of an isolation center because they have no food.

The Liberia Broadcasting System says the 43 people were put in quarantine after four people died of Ebola in an impoverished corner of Grand Cape Mount County, near the Sierra Leone border.

It said the U.N. World Food Program apparently stopped providing food to people affected by Ebola in the area.

Liberia is the hardest-hit of three West African nations being ravaged by Ebola. U.N. World Health Organization figures say the country has 4,665 infected people and 2,705 have died there.
