NEW DELHI, Dec. 8 — A senior Indian spokesman today disputed statements by a White House spokesman that Indian military incursions into East Pakistan had wrecked American efforts to persuade the Bengali insurgents and the Pakistan authorities to reach a political settlement.

The Washington statements are “contrary to facts and without understanding of the situation,” the official said.

“To say that the Government of India hindered any peace efforts is totally wrong,” he added.

He said the proposals the United States had made for a political settlement were neither new nor realistic.
