Aung Gyi, a retired army officer who broke with strongman Ne Win and became the country's leading dissident, was named chairman Tuesday of a newly formed opposition alliance.

The alliance urged workers to continue a general strike until they achieved their goal of democracy. The strike began Sept. 18 when Gen. Saw Maung seized power in a military coup.In another development, the government said Tuesday that 348 people had been killed in Burma since the coup.

Government spokesman Kyaw Sann told a press briefing that 219 others had been wounded and 1,107 arrested by authorities. The greatest number of deaths, 249, occurred in Rangoon, he said.
