UGANDAN forensic experts extended a gruesome investigation on Tuesday into a doomsday sect which appears to have murdered more than 500 people in a church blaze and other mass killings in Uganda. Thirteen more bodies have been found buried beneath a house belonging to one of the leaders of the cult. The 13 bodies, which include those of five children, were found under the concrete floor of a room in the former home of Dominic Kataribabo in the southwestern town of Rugazi. Police in Mbarara in the south west of the country said that doctors and criminal investigators are to inspect three new sites on land belonging to the cult known as the Movement for the Restoration of the Ten Commandments of God. On Monday, more than 60 bodies were dug up by prisoners brought to the nearby village of Rugazi, on land owned by one of the four top leaders of the cult, Dominic Kataribabo. At least 330 sect members died in a fire that was triggered by a bomb blast in their makeshift church at Kanungu over a week ago.
