Russia has been banned from the 2018 Paralympic Games, officials announced Monday, refusing to lift a restriction because of what they called an insufficient recovery from the Russian doping scandal.

Nonetheless, those officials said, certain disabled Russian athletes will have the opportunity to compete at the coming Winter Games — a decision taken with some disagreement among top Paralympics executives, who were unanimous in their decision not to lift the ban.

“What was uncovered was not a minor breach of an obligation,” Andrew Parsons, president of the International Paralympic Committee, said at a news conference in Bonn, Germany on Monday. “This was an orchestrated attack on the integrity of sport.”

Justifying the continued ban, Mr. Parsons pointed to Russian officials’ lacking cooperation with global sports regulators as well as their failure to acknowledge the evidence of systematic cheating laid out nearly two years ago.
