A NATO jet blasted two fuel tankers hijacked by the Taliban in northern Afghanistan, setting off a huge fireball Friday that killed up to 90 people, Afghan officials said, AP reported. The NATO command said a «large number of insurgents» were killed or injured in the pre-dawn attack near the village of Omar Khel in Kunduz province. An Afghan police officer said the 90 dead included about 40 civilians who were siphoning fuel from the trucks. He spoke on condition of anonymity because of the sensitivity of the information. The top NATO commander, Gen. Stanley McChrystal, has ordered curbs on airstrikes after a strong backlash among Afghans against the high number of civilians killed in such military operations. Police Chief Gulam Mohyuddin said Taliban fighters stopped the vehicles as they were about to cross the Kunduz River. Navy Lt. Cmdr. Christine Sidenstricker, a public affairs officer, said NATO warplanes attacked and destroyed the two tankers after determining that there were no civilians in the area. She said that NATO and the Afghan government are investigating reports of civilian casualties. Another NATO spokesman said one reason the fuel tankers were targeted was they are frequently used in suicide attacks. -- SPA
