British Soldiers Injured In 'Insider Attack' In Afghanistan, Two-Star US General Killed

A soldier has been killed and a number of Britons injured in a suspected "insider attack" at a military academy in Afghanistan. The incident happened at the Afghan National Defence University in Kabul city when a man reportedly dressed in Afghan army uniform opened fire on foreign troops.

The International Security Assistance Force (Isaf) confirmed one of its soldiers was killed, while Germany's Ministry of Defence said an army general was among 15 people injured. It is understood a number of Britons were wounded in the attack but their injuries are not thought to be life-threatening.

A US official said the soldier killed was American, the Associated Press reported. The UK's Ministry of Defence said it was investigating reports of a shooting incident and "it would be inappropriate to comment further at this time". The incident took place at the site in the Qargha district of Kabul which also houses a British-run military academy - dubbed "Sandhurst in the sand".

A spokesman for Germany's Ministry of Defence said: "There has been an attack, probably through an 'inside attacker' 12.23pm Afghan time on August 5. At least 15 Isaf members were wounded, among them a German soldier who works as a brigade general. One Isaf soldier died from his injuries.

"The German general, who is not thought to be in a critical condition, is receiving treatment. His next of kin have been informed. An investigation into the attack is taking place." An MoD spokesman said: "We are aware of reports of an incident at Qargha. The incident is under investigation and it would be inappropriate to comment further at this time".

An Isaf spokesman said: "Isaf confirms that an incident occurred today involving local Afghan and International Security Assistance Force (Isaf) troops at The Marshal Fahim National Defence University in Kabul City, Afghanistan. "At this time, Isaf can confirm one Isaf service member was killed. This incident is under investigation. It is Isaf policy to defer casualty identification to the relevant national authorities."

General Mohammmad Zahir Azimi, a spokesman for Afghanistan's Defence Ministry, told the Associated Press a "terrorist in an army uniform" opened fire on both local and international troops. He said the shooter had been killed and that three Afghan army officers were injured.

A US official said one American soldier was killed in the attack and "about a dozen" of those wounded were Americans, AP reported. The attack was initially reported to have happened at the British-run training academy, dubbed "Sandhurst in the sand", which will be the only remaining British military presence in the country after operations end this year.

However it is understood the incident happened in another part of the large site at Qargha, where there are several training facilities. The attack comes as so-called "insider attacks" - incidents in which Afghan security forces turn on their Nato partners - largely dropped last year. In 2013, there were 16 deaths in 10 separate attacks. In 2012, such attacks killed 53 coalition troops in 38 separate attacks.
