And 7 more Americans were injured when a grenade was tossed over the security fence at a NATO base.

Seven U.S. military trainers were wounded on Sunday when a grenade was thrown at their base in northern Afghanistan, police said, as anti-Western fury deepened over the burning of the Koran at a NATO base.

Despite an apology from U.S. President Barack Obama, riots raged across the country for a sixth day on Sunday against the desecration of the Muslim holy book at a NATO air base at Bagram. Some protesters hoisted the white Taliban flag.

The Afghan Interior Ministry identified one of its employees as a suspect in the fatal shooting of two U.S. officers in its headquarters a day earlier, an attack that prompted NATO to recall its staff from ministries.

One civilian was killed, 15 more were wounded and three policemen injured in riots near the NATO base in northern Kunduz province, where the blast that wounded the Americans took place, regional police chief Samihullah Qatra told reporters.

NATO confirmed there had been an explosion outside one of its bases in northern Afghanistan, but declined to comment on casualties.

The protests have killed 30 people and wounded 200, including two other U.S. troops who were shot dead by an Afghan soldier who joined rallies in the country's east.

The Koran burnings could make it far harder for NATO forces to win the trust of the Afghan public as they try to stabilize the country ahead of the withdrawal of foreign combat troops at the end of 2014.

Afghan security sources identified Abdul Saboor, a 25-year-old police intelligence officer, as a suspect in the shooting of the Americans at close range inside the Interior Ministry.

If our guys have to be looking over their shoulders at the men they are supposed to be training to make sure they don't get shot in the back, the mission is already a failure and we should bring the troops home. If the Afghan people want the kind of government the Taliban will give them, and if they want to continue to live in the 14th century, who are we to say otherwise?

Let them stew in their own hate.
