Up to 50 Taleban insurgents have been killed in Afghanistan's western Farah province after clashes that left seven Afghan and two US soldiers dead, government officials said Sunday. Militants fired mortar rounds at a military-escorted convoy of humanitarian supplies in Farah province on Saturday, sparking clashes, explosions and an air strike by NATO forces. “The information we received from the ANA (Afghan National Army) is that in this clash seven ANA soldiers were killed and 12 were wounded,” Farah governor Rohul Amin Amin said. “Around 40 to 50 Taleban were killed. Two American soldiers were killed. One ISAF vehicle was damaged,” he said. “NATO airplanes then bombed, and the information we have received was that the casualties were not significant from the airstrike.” Cholera outbreaks Afghanistan has reported outbreaks of potentially lethal cholera in 10 provinces across the impoverished country, the health ministry said. The ministry “has so far recorded 673 cases countrywide” of the highly contagious disease in almost a third of the country's 34 provinces, including in the capital Kabul. No deaths have been reported.
