Lithuanian President Vytautas Landsbergis said Friday he had received U.S. assurance of support for his Baltic republic, which is trying to buck a crackdown by Soviet troops.

In Washington, President Bush told a news conference he had spoken with Soviet President Mikhail Gorbachev and called for a peaceful solution in the Baltics.The Soviet crackdown had prompted the U.S. administration to reconsider holding a summit between Bush and Gorbachev in Moscow on Feb. 11-13. But Marlin Fitzwater, the White House spokesman, said Friday the summit is still on.

That didn't prevent U.S. officials, however, from unleashed a barrage of criticism at the Soviet media, saying tension in Lithuania had been heightened by biased reporting.
