A powerful typhoon pounded South Korea with strong winds and heavy rain Tuesday as it churned up rough seas that smashed two fishing ships into rocks, killing at least five fishermen and forcing the coast guard to perform a daring rescue for the survivors. Rescuers saved 12 fishermen and were still searching for 10 missing from the Chinese ships that hit rocks off South Korea's southern Jeju island. Separately, at least three other people died as Typhoon Bolaven knocked out power to hundreds of thousands of South Koreans, canceled flights and temporarily halted joint war games by U.S. and South Korean military forces, according to a report of the Associated Press.
