(CNN) -- American missiles were used in an attack that killed 55 people, including 41 civilians, in southern Yemen, Amnesty International said Monday.
The human rights organization released what it said were photographs of a U.S.-manufactured cruise missile used in the December attack in the community of al-Ma'jalah, and said authorities must be held accountable.
"Based on the evidence provided by these photographs, the U.S. government must disclose what role it played in the al Ma'jalah attack, and all governments involved must show what steps they took to prevent unnecessary deaths and injuries," said Philip Luther, deputy director of the organization's Middle East and North Africa program.
