Salvadoran migrants rest at the "Hermanos del camino" (Brothers of the road) shelter in Ixtepec, in the state of Oaxaca Dec. 22, 2010. About 50 Central American immigrants were kidnapped in Mexico when armed men stopped the cargo train they were riding and abducted all of the women aboard, El Salvador said on Tuesday. Mexico's interior ministry said it had found no evidence backing the Salvadoran claims of the disappearance in the state of Oaxaca, in southern Mexico.
