Liberian Youth in U.S. Find Threat from New Violence

Liberians who fled their country's civil war and settled in southwest Philadelphia during the 1990s thought their troubles would be over.

Instead, their children were taunted and attacked by fellow students. Liberians in Philly eventually banded together to fight back, and the attacks subsided.

But now, parents worry these new Liberian gangs are fueling another kind of violence.
