KABUL (AFP) - Eight foreign soldiers died in one day in Afghanistan, officials said Sunday, including four in a single incident believed to have been a vehicle accident. The four died Saturday of non-battle related injuries in southern Afghanistan, the Nato-led International Security Assistance Force (Isaf) said in a statement. That incident, in a region containing many of Afghanistans bloodiest battlegrounds, came on a day when Isaf said four other foreign soldiers also died in separate insurgent attacks three in the south and one in the east. In line with policy, Isaf did not give further details of what happened in any of the incidents, or the nationalities of the troops who died. There are 130,000 international forces in Afghanistan, of which 90,000 are from the United States. A total of 256 international troops have now died in Afghanistan this year, according to an AFP tally based on that kept by the independent iCasualties.org website. The total for the whole of 2010 was 711. Separately, three Afghan civilians were killed Sunday and 11 wounded when a suicide car bomber targeted a passing foreign forces convoy in the northern city of Kunduz, the Afghan interior ministry said. It added that there were no foreign force casualties. Germany has a significant force presence in Kunduz, part of the northern region which has seen escalating violence in recent months. Two German soldiers were killed last month in an attack which killed the regional police chief. The commander of Nato forces for northern Afghanistan, German General Markus Kneip, survived the attack with slight injuries.
