Afghan President Hamid Karzai is meeting with President Bush today in Washington. Karzai — as well as the United Nations — has called for an investigation into new reports of U.S. soldiers abusing detainees in Afghanistan. In one incident, a 22-year-old taxi driver died after being hung from the roof of his cell by his wrists. During his trip to Washington, Karzai is expected to ask Bush to allow the Afghan government to be given more power from the U.S. military. The Observer of London has reported Karzai is facing bitter criticism in Afghanistan for heavy-handed US military tactics.
