Asian stock markets tumbled in early trading as fresh worries over debt woes in Europe dampened sentiment across the region.
Japan's benchmark Nikkei 225 stock average dropped 176.35 points, or 1.7 percent, to 10,286.16.
South Korea's Kospi lost 1.8 percent to 1,6664.64. Australia's S&P/ASX 200 index was also down 1.7 percent at 4,561.00.
Sentiment in Asia turned downbeat on growing concerns that cost-cutting fiscal measures being taken by Greece, Portugal and Spain could hamper a recovery in the eurozone economy.
On Wall Street on Friday, the Dow Jones industrial average fell 162.79 points, or 1.5 percent, to 10,620.16 on fears that such austere measures in Europe would slow economic activity on the continent and elsewhere.
