(AP Photo/Allauddin Khan) (Newser) – The latest attacks on Westerners by Afghans have claimed three lives and wounded several other people. An Afghan policeman this weekend shot a trio of civilian police training advisers, two American and one British, Afghan and NATO authorities say. Two other people, including an Afghan training adviser, were wounded in the incident. Separately, an Afghan soldier wounded two NATO troops after opening fire in northern Afghanistan today, the AP reports. The police-uniformed gunman was killed after the attack at a police training academy. Uniformed Afghans have now killed 26 foreign troops this year; last year, the figure was 35 in 21 fatal attacks, while the previous year saw 20 killed in 11 attacks. Just four attacks occurred in 2007 and 2008 combined.
