The human rights group has called on the US to reveal details of the alleged secret detention of suspects abroad.

Amnesty fears the case is part of a "much broader picture" in which the US holds prisoners at secret locations.

The US has not responded to the claims, but the head of the CIA recently said the agency does not use torture.

Porter Goss said in testimony to the US Senate torture was neither professional nor productive.

Beaten on feet

In the new report, Amnesty has urged the US to reveal where its alleged secret detention facilities are, stop using them and name the detainees held there.

The two Yemeni men, Muhammad Faraj Ahmed Bashmilah and Salah Nasser Salim Ali, were arrested separately but reported almost identical experiences to Amnesty.
