7 US military injured in Afghanistan attack at NATO base.

RTE News - Seven US military trainers have been injured at a NATO base in northern Afghanistan.
Protesters in Kunduz, northern Afghanistan threw a grenade at their base.
NATO's International Security Assistance Force (ISAF) has confirmed there had been an explosion outside one of its bases in northern Afghanistan, but declined to comment on casualties.
Meanwhile, police are looking for an Afghan intelligence officer suspected of killing two US officers in a shooting at the interior ministry in Kabul.
Yesterday, NATO pulled its entire staff out of Afghan government ministries after the shooting, which came as anti-US protests raged for a fifth day over the burning of Korans at a US-run military base.
Local television quoted a source as naming the suspect as a 25-year-old who had studied in Pakistan and joined the ministry as a driver in 2007 before being promoted.
He had signed into the ministry on yesterday before disappearing. The two US officers were found dead in their office with gunshot wounds.
Taliban insurgents have claimed responsibility for the shooting, saying it was in revenge for the Koran burning - an incident that forced US President Barack Obama to apologise to the Afghan people.
NATO, which has a 130,000-strong US-led military force fighting an insurgency in Afghanistan, has advisors throughout the Afghan government but commanding officer General John Allen ordered them all withdrawn after the shooting.
In a statement, the Pentagon said the US condemned the killings "in the strongest possible terms".
The Taliban said in a website statement that it carried out the attack in response to the burning of copies of the Koran.
NATO's spokesman Brigadier General Carsten Jacobson said the shootings may not be directly linked to the protests.
