Stock market trading around the world Tuesday was uneven as investors appeared uncertain where to turn next in the ongoing international financial turmoil and new trouble spots emerging.

While investors continued to look for signs about whether the US finance sector 700-billion-dollar bail-out plan would start to show results, the focus of international concern was suddenly turned on tiny Iceland, where the government passed emergency laws to prevent the country's overstretched banking system from going under.

At the same time, in data underlining the extent of the crisis, the International Monetary Fund warned that US financial sector losses could total 1.4 trillion dollars as a housing crisis at the centre of the global turmoil has yet to reach its peak.

In a bid to try to stabilize conditions, the European Central Bank in Frankfurt provided a further infusion of 250 billion euros (338 billion dollars) to commercial banks in a regular one-week loan at an interest rate of 4.99 per cent. The volume was 60 billion euros higher than last week's loan.

In addition to the weekly loan, the ECB also pumped 50 billion dollars into interbank money markets, the same amount as Monday.

In London, the FTSE-100 in the midst of a roller-coaster ride was up by by 1.7 per cent, or 76 points, to 4,665.2 points at lunchtime, after surging ahead by almost 3 per cent in early morning trading.

On Monday, the FTSE plunged by almost 8 per cent in the largest one-day percentage decline since 1987.

In Frankfurt, the DAX 30 during a day of volatile trading was down a slight 0.25 per cent to 5,373 points at mid-afternoon. Financial institutes were among the losers, led by Deutsche Bank, Germany's biggest, which was off 7.4 per cent at 44.30 euros.

Troubled property lender Hypo Real Estate, which is subject of a 50-billion-euro (68-billion-dollar) bail-out after running into liquidity problems, saw its shares climb 4 per cent to 4.89 euros, following news that its chief executive had stepped down.

Carmaker Volkswagen posted gains of 19.2 per cent to stand at 348.66 euros, while Daimler AG was up 5.29 per cent at 28.64.

In Paris, the CAC-40 was up almost 2.6 per cent at mid-afternoon to 3,807.74 points, in trading a day after the bourse had suffered its largest single-day loss in its 21-year history. Advancing issues outpaced losers by 3 to 1.

In Milan, the bourse rebounded Tuesday from the previous day's heavy losses with the S&P/Mib benchmark index up by 2.38 per cent to 24,342 points in afternoon trading. Leading the charge were bank Intesa Sanpaolo up by 7.59 per cent and energy group Eni whose value rose 3.85 per cent.

The surge followed some jittery morning trading when telecommunications group Telecom, industrial giant Fiat and bank Banco Popolare were all suspended from trading due to losses.

Elsewhere in Europe, in Madrid the Ibex-35 index had gained 3.33 per cent to 11,083 points by mid-afternoon. The Santander, Banco Bilbao Vizcaya Argentaria (BBVA) and Banesto banks gained more than 4 per cent. The energy company Gas Natural soared by 8.37 per cent.

In Amsterdam, the main AEX index remained volatile, first rising, then falling, before then gaining again, with a 1330 GMT reading of 316.50 points, up 1.26 per cent. Insurer Aegon and bank and insurance company ING Group were among the losing shares.

In the Baltic region, the guideline Baltic Benchmark Index (BBI), which includes data from the Tallin, Riga and Vilnius exchanges, closed 6.08 per cent lower at 339.88.

In the Nordics region, the OMX Stockholm 30 benchmark index was flat mid-afternoon Tuesday after closing down 7.1 per cent on Monday, the biggest drop since the September 11, 2001 terrorist attacks in New York. In Copenhagen, the OMX Copenhagen 20 Index was down 0.3 per cent while in Helsinki the decline was just over 1 per cent.

In Oslo, the bourse was also hovering in positive territory after closing dropping nearly 10 per cent on Monday.

In Vienna, the leading ATX index was down by 4.54 per cent by mid- afternoon. Companies exposed to business in Central and Eastern Europe suffered the biggest losses, such as Raiffeisen International Bank-Holding AG, which was down 8.51 per cent.

Earlier in Asia, the Tokyo, stocks continued their downward course, as the Nikkei plunged below 10,000 for the first time in nearly five years before recovering slightly at Tuesday's closing.

But Australia's stocks managed a modest gain after the Reserve Bank of Australia (RBA) delivered a bigger-than-expected cut of one per cent in its key rate. The mid-morning announcement triggered a rise on the market, with the AXS 200 finishing 78 points, or 1.7 per cent, higher at 4,618 points.

In Seoul, the benchmark Kospi index rose 7.35 points, or 0.5 per cent, to close at 1,366.10. But the main index of the technology- heavy Kosdaq market slipped 4.44 points to 401.95.
