An explosion killed two occupants of a car near the Kazakh security service's remand centre in the capital Astana on Tuesday, shattering the windows of nearby houses, the Interior Ministry said. The ministry said the blast, which occurred in the early hours of the morning, was not linked to terrorism. It said an explosive device appeared to have detonated automatically inside the red Audi-100, which had been parked on waste ground. "The given circumstances indicate the absence of any signs of a terrorist act," the ministry said in a statement on its website, www.mvd.kz. It said the explosive device did not contain any shrapnel. The ministry said the two occupants of the car who were killed in the explosion were male and of European appearance, according to a report of Reuters.
