Soviet tanks and troops patrol the streets of the Georgian capital of Tbilisi, following a bloody clash between Red Army troops and Georgian nationalist protesters Sunday. The Foreign Ministry said Communist Party chief of Soviet Georgia offered to resign Wednesday after local leaders met to discuss the clash that left 19 people dead. President Mikhail S. Gorbachev appealed for calm and an end to the demonstrations, the Tass news agency said. In an address to the Georgian people, which was published in the republic's capital, the Soviet leader said the demonstrations "damaged the interests of perestroika, democratization and renewal in the country." The resignation offer and the appeal from Gorbachev came as scattered strikes continued in the southern republic.
