SHEEN, SAGAN ARRESTED

MERCURY, NEV. -- MERCURY, NEV. -- Actor Martin Sheen and astronomer Carl Sagan were among 438 antinuclear activists -- including the crew of a hot-air balloon -- arrested at the Nevada Test Site, where more than 1,000 activists gathered.

It was the largest demonstration in more than six years of protests at the site and was held even though the first nuclear test of the year had been detonated Tuesday, two days ahead of schedule.

The Soviet Union has said the test would end the Kremlin's 18-month moratorium on testing.

Rep. Thomas J. Downey (D-N.Y.), who led a congressional delegation, told the demonstrators, "Your voice is being heard in Washington. We are going to end nuclear testing."
