Asia-Pacific markets tumbled Thursday, led by Hong Kong's Hang Seng index dropping over 2%, following the U.S. Federal Reserve's decision to hold interest rates steady. Investor sentiment was further dampened by the Israel-Iran conflict. Meanwhile, President Trump convened national security advisors for a second day to discuss potential military action against Iran. Wall Street closed mixed, with the Dow down slightly and the Nasdaq up marginally.
