KABUL (AFP) - Nato said Wednesday that a foreign soldier had been killed in an insurgent attack in southern Afghanistan, where the fight to wipe out the Taliban is at its fiercest. The soldier, whose nationality was not revealed, died on Tuesday, Natos International Security Assistance Force (ISAF) said in a brief statement. The death brings to 541 the number of foreign soldiers to die in the Afghan war so far this year, according to an AFP tally. The 2009 toll was 521. Nato and the United States have more than 152,000 soldiers in Afghanistan fighting the Taliban-led insurgency, which has intensified to its most virulent since the Islamists regime was overthrown in late 2001.
