Afghan President Hamid Karzai is threatening to delay a security pact with the United States despite its ratification by a tribal council he convened. A gathering of elders, known as a loya jirga, approved an agreement Sunday that would keep U.S. military bases and thousands of troops in Afghanistan beyond the planned 2014 withdrawal. U.S. troops would also receive immunity under Afghan law. But in his closing remarks to the meeting, Karzai said he would continue negotiations with the United States and demand an end to raids on Afghan homes.

Afghan President Hamid Karzai: “While we’re ready to give bases for Americans on our soil, we have a condition concerning security — security from today onwards meaning from now on American forces are banned from launching operations on Afghan homes.”

In his remarks, Karzai accused U.S. forces of killing two innocent villagers in a raid last week. The United States says the victims were militants. In addition to ending home raids, Karzai also called on the United States to reach a peace deal with the Taliban. While Karzai has pledged to delay his signature, the Obama administration has insisted on the deal’s ratification before the end of the year.
