An Afghan official accused Pakistan's top spy agency of organizing an assassination attempt on President Hamid Karzai, the most serious in a string of allegations which was outright rejected by Pakistan as concocted lies. Afghan intelligence chief Amrullah Saleh alleged last month that suspects involved in the attempt on Karzai had exchanged cell phone text messages with people in Pakistan's lawless tribal regions and the city of Peshawar. But Saleh's spokesman, Saeed Ansari, went further Wednesday, claiming Afghan intelligence could prove Pakistan's Inter-Services Intelligence (ISI) was involved. “The evidence and documents as well as the confessions of people arrested by the intelligence service shows that the main organizer of the terrorist acts during the 16th anniversary of the Mujahideen victory was the intelligence service of Pakistan and its allies,” Ansari said. Pakistan's Defense Minister Chaudhry Ahmed Mukhtar dismissed the accusation that the country's main military intelligence agency was involved. “It appears to be a concocted statement. They often made such statement to instigate but we don't accept it. We believe they are lying,” Ahmed was quoted as saying. “Such statements will have a negative impact on the ongoing war on terror. They should think and refrain from giving such statement against their partner in the war,” he said. Karzai escaped unharmed when assailants opened fire with guns and mortars in Kabul in April. __
