U.S. Says Deadly Afghan Protests 'Must Stop'

U.S. Secretary of State Hillary Clinton said Sunday that deadly protests in Afghanistan over the burning of Korans by U.S. soldiers "must stop".

"We deeply regret the incident that has led to this protest, but we also believe that violence must stop and the hard work for building a more peaceful and secure Afghanistan must continue," she told a news conference during a visit to the Moroccan capital Rabat.

On Sunday, a protester was killed and seven U.S. soldiers were wounded in a grenade attack on their base in a sixth day of anti-American protests, police said, bringing the death toll to more than 30 since the Koran burning at the Bagram airbase north of Kabul.
