UNITED NATIONS, N.Y., Nov. 1--The U.N. abruptly ended its debate on the Turkish-Syrian crisis today after Syria announced it was ready to leave the problem for the present without any action.

Syria's decision was part of a formula worked out behind the scenes, to avoid a showdown in the bitter two-week discussion.

A seven-nation group acted similarly on its own counterproposal to put Secretary General Dag Hammarskjold into the situation, if needed, as a mediator.

At a news conference later, Syrian Foreign Minister Salah Bitar declared that Syria was endangered as long as Turkish troops concentrate near the Syrian-Turkish frontier.

LONDON, Nov. 1--Reports from Moscow tonight said Soviet armed forces are being purged of powerful friends of ex-Defense Minister Georgi K. Zhukov and the marshal himself is likely to be exiled to a remote military job.

Already, according to reports reaching Belgrade, he has been expelled from all his positions of power--from the top-level party Presidium, the party Central Committee and the Defense Ministry job.
