Foreign Minister Shah Mehmood Qureshi believes the attempted New Yorks Times Square bombing is a reaction to US drones targeting Taliban followers along the Pak-Afghan border. "This is a blow back. This is a reaction. This is retaliation. And you could expect that. Let's not be naive. They're not going to sort of sit and welcome you eliminate them. They're going to fight back," CBS News quoted Qureshi, as saying. Qureshi was speaking as police confirmed the arrest of two people, one of whom, Tauseef Ahmed, is believed to have travelled to the U.S. to meet Faisal Shahzad. Both were arrested in Karachi, Pakistan. CBS News has also learned that Shahzad may have spent at least four months training at a terrorist camp - raided in early March by Pakistani forces.
