WASHINGTON/NEW YORK - US President Bush said on Monday that he wanted Osama bin Laden “dead or alive” for last week’s attacks on the World Trade Center and the pentagon, but many of Washington’s allies are cool on strikes against Afghanistan.

  Bush has named Saudi - born militant Osama bin Laden as a prime suspect, though he has provided no evidence for his claim. Still, he had been building public support for military action and has warned Afghanistan’s Taliban to give up Bin Laden.

  But the Taliban, which has warned of “holy war” in response to any US attack, by Tuesday afternoon had given no indication of whether the man they call their“ guest” would be handed over.

  On an unprecedented“ Day of terror”, two planes smashed into New York’s World Trade Center twin towers on September 11, putting them into ruins while explosions rocked the Pentagon in Washington, and the White House and State Department were evacuated. The attacks have left more than 5, 000 people dead or missing.

  China has said it is ready to join international efforts in fighting “terrorism ”but insisted that peace, not war, is the best option.

  In London, Blair declared it a“ war between the civilized world and fanaticism ”and determined to stand by an ally which aided Britain in two world wars. France, Germany and other, including Russia, are also supportive. “The evil must be punished, ” Russian President Vladimir Putin said. “But we should not liken ourselves to bandit.” His defense chiefs have ruled out hosting NATO forces in former Soviet Central Asia or joining US military action, although Moscow says it will help with intelligence.
