An emotional Afghan President Hamid Karzai on Saturday urged international troops to stop their operations in our land, his strongest criticism yet of mistaken killings of civilians. Karzais comments came after a week in which a relative of his was killed in a raid by foreign forces and he rejected an apology by the US commander of troops General David Petraeus for the deaths of nine children in a Nato strike. "I would like to ask Nato and the US with honour and humbleness and not with arrogance to stop their operations in our land," Karzai said in Pashto as he visited the dead children's relatives in Kunar province, eastern Afghanistan. "We are very tolerant people but now our tolerance has run out." In an apparent reference to Pakistan, he said international forces "should go and fight this war where we have showed them (it is) over the last nine years." Insurgents have hideouts in Pakistan's lawless border regions.
