Brazilian stock market two-year low

Brazilian stocks have fallen by more than 4% to their lowest level for two years.

Analysts said this was because of concerns about the effect possible retaliation by the United States - after Tuesday's attacks on the World Trade Centre in New York and the Pentagon in Washington - could have on world markets.

The Sao Paolo stock exchange index, Bovespa, fell 472.8 points, or 4.6 per cent, after only 25 minutes trading.

The Brazilian currency, the Real, also fell 1.39% against the dollar.
