In an apparent conciliation, a Soviet military official has promised not to seize the Lithuanian parliament building and nationalist officials agreed to hold a referendum on independence.

But Friday, some parliament members and officials claimed that Soviet troops have stopped people at random and rounded up Lithuanian youths for military service. An account that someone was crushed to death under an army vehicle could not be immediately confirmed.Vergilius Cepaitis, head of the separatist Sajudis group in the Lithuanian parliament, announced Thursday that a "poll" of registered voters would be taken on the statement: "The state of Lithuania is an independent, democratic republic."

"You can call it a kind of compromise with Moscow," he said.

Kremlin officials have long demanded that the Baltic republic of 3.7 million people hold a referendum on secession. Lithuanian authorities had refused.

There was no immediate clarification of when the vote would take place or whether it would be binding.

In Vilnius on Thursday, Maj. Gen. Yuri Nauman said Soviet troops would not try to surmount barricades erected around the Lithuanian parliament. The blockades were put up after Soviet soldiers stormed the republic's broadcasting center early Sunday, killing 14 people and injuring 230.

"Such an action will not be taken. It's simply not needed by the military," said Nauman, a representative of the Soviet Defense Ministry.

Hundreds of nationalists continued to guard the parliament Friday. Many slept on couches or in sleeping bags during the day. Their scanty arms included hunting rifles and shotguns, some of which looked 50 years old.

President Mikhail S. Gorbachev ordered troops to the Baltics last week because of growing defiance of the Soviet military draft. Lithuania, annexed by the Soviet Union at the start of World War II, declared independence in March.
