MADRID, Oct. 10 (Xinhua) -- The Spanish Bourse registered Friday the biggest drop in its history amid spreading panic on the world financial markets.

    Spain's benchmark stock index, the Ibex-35, plummeted 9.14 percent and finished the session under 9,000 points, losing more than 900 points in a single day.

    Overall, the Spanish Bourse lost more than 20 percent of its value in one week given the losses on previous trading days.

    Stock markets across Europe also experienced a dramatic drop Friday, with London losing 8.6 percent, Paris and Frankfurt 7.6 percent and Milan 7.1 percent.

    According to economists, stock market trading will remain hectic until there is a global common action to solve the current financial crisis, which is considered the worst since the "Great Depression" in 1929.
