President George W Bush warned Tuesday that suspected terrorist mastermind Osama Bin Laden`s al-Qaeda network seeks chemical, biological and nuclear weapons "They are seeking chemical, biological and nuclear weapons. Given the means, our enemies would be a threat to every nation and eventually to civilization itself," he said via satellite to Eastern European leaders at an anti-terrorism summit in Warsaw. "Today our freedom is threatened once again," Bush said equating terrorism with the erstwhile Soviet Union. Bureau Report
