Riots over Quran burning have continued for almost a week now. The protests have killed 30 people and wounded 200, including four U.S. troops who were shot dead by an Afghan soldier. Seven U.S. military trainers were wounded on Sunday when a grenade was thrown at their base in northern Afghanistan, police said. Anti-American protests continue in Afghanistan, in spite of apologies by the U.S. military and President Obama. According to Reuters, NATO has described the incident of burning of the Koran at the Bagram air base as a tragic blunder. U.S. Secretary of State Hillary Clinton said Sunday that such unrest and targeting of Americans has gotten "out of hand" and needs to stop.
