WASHINGTON, Nov. 27 (AP) — President Nixon is reportedly sending messages to the leaders of India, Pakistan and the Soviet Union this weekend in hopes of heading off a general Indian‐Pakistani war.

The Nixon appeals were said to focus on defusing the explosive military situation by urging disengagement of Indian and Pakistani forces in East Pakistan and their mutual withdrawal.

The Presidential messages, scheduled to be delivered in the three capitals shortly, were described as similar to a plea made by Secretary of State William P. Rogers last Wednesday to the Indian and Pakistani Ambassadors here.

United States diplomats have also been in touch with the Soviet Union on the issue. The United States belief is that the Russians also want to avert an Indian‐Pakistani war and that Moscow may have added influence with New Delhi be cause of the increasingly close Soviet‐Indian relationship.
