A landslide collapsed the ceiling of a Shiite shrine in central Iraq over the weekend and killed at least seven people, including a child, officials said Monday as rescuers continued to search for survivors. The landslide struck Qattarat al-Imam Ali shrine near the holy city of Karbala, about 80 kilometers (50 miles) south of Baghdad, on Saturday. According to Iraq's civil defense, the landslide hit the ceiling of the shrine, which lies in a natural depression, causing it to cave in and dumping a stream of rock and mud inside the structure. The entrance, walls and the minarets of the shrine, which was built on the place of a water source in the desert, remained standing.
