Ninety-two Somali deportees were forced to sit on a plane for almost 48 hours in "completely appalling" conditions with shackles on their hands and feet, says a lawyer representing two of the men.

Immigration and Customs Enforcement (ICE) attempted to deport the men on Dec. 7, but the flight returned to the U.S. after sitting on a runway in Dakar, Senegal, for 23 hours — during which time some of the men urinated on themselves.

A lawsuit filed in U.S. District Court in Miami alleges ICE agents "kicked, struck, choked and dragged detainees" during the journey. The allegations have not been proven.
