Three foreign soldiers were killed in two separate Taliban-style bomb attacks in Afghanistan's volatile south, NATO said Friday. The three, whose nationalities were not released, were all killed on Thursday, NATO's International Security Assistance Force (ISAF) said. A total of 408 foreign troops have died in the Afghan war so far this year, according to an AFP tally based on that kept by the website. The toll for July is 86, compared with 102 in June which was the worst month for foreign military casualties since the end of 2001. NATO and the United States have close to 150,000 troops in the country, with 30,000 deployed to the southern Taliban heartland in Helmand and Kandahar provinces.
