Nuclear Talks Recess 5 Weeks

GENEVA — U.S. and Soviet negotiators, blaming each other for blocking any substantive progress, called a five-week recess today in the latest round of talks on limiting nuclear testing.

The negotiations have bogged down over U.S. insistence that the talks focus on ratification of test limitation treaties reached in 1974 and 1976, and Soviet demands for discussions on new, lower limits and an eventual ban on testing.
