Country's superior spy agency Inter Services Intelligence (ISI) has decided to go after Talibans Supreme leader Mullah Omer before the Americans have a chance to repeat their operation against Osama bin Laden, a British newspaper quoted sources as saying. A senior ISI official requesting not to be named told the newspaper that there would be huge military operation in Quetta very soon where Omar is believed to have been stationed. He said that the agency would try to take him alive while he could be killed if he would put up resistance.
