British journalist Robert Fisk is reporting that Israel may have dropped uranium-based munitions on targets during its war against Lebanon. A leading British scientist has found that soil samples in Lebanon show elevated radiation and the concentration of uranium isotopes. According to the scientist, Dr. Chris Busby, there are two possible reasons for the contamination. Israel might have dropped a small experimental nuclear fission device or Israel used a bunker-busting conventional uranium bomb that employed enriched uranium. Robert Fisk reports that a photograph of one explosion shows large clouds of black smoke that might result from burning uranium. Israel has denied the report. However, last week the Israeli military admitted for the first time that it had dropped phosphorous bombs on Lebanon.
