World financial markets affected by Japan crash
Japanese shares have tumbled again, as worries spread about the impact of the quake.
The Nikkei Index ended the day more than 10% down. It is the biggest one-day fall since 2008, at the start of the global financial crisis.
Markets across Asia also fell sharply. At the same time, the Bank of Japan has flooded the money markets with more cash, pumping in almost $100bn.
