Witness have testified about a litany of horrors in the trial of Guatemala's former U.S.-backed military strongman, describing to judges the shelling of villages, beheadings and body parts kicked around like soccer balls.

After several days of testimony from women subjected to sexual violence, judges in the trial of Efrain Rios Montt heard Thursday from the victims of massacres, and from forensic experts.

Rios Montt is on trial along with his former head of intelligence in connection with the deaths of 1,771 Mayan Indians during the military dictatorship he led from March 23, 1982 to Aug. 8, 1983, during which he led a U.S.-backed counterinsurgency against leftist guerrillas.
