The US Administration has asked Pakistan to show concrete actions to prove its commitment in the war against terrorism. A statement came from the State Department in this regard amid increasing questions being raised by US lawmakers and think tanks on Pakistan's commitment to fight against terrorism. State Department spokesman Mark Toner told reporters in Washington that the United States has asked a number of questions to Pakistan with regard to the hideout of Osama bin Laden in an affluent suburb of Islamabad. He also said that US-Pak counter terrorism cooperation that had been going on since 9/11 has borne fruit and had led to some successes. He said it has put increased pressure on al-Qaida and other terrorist groups operating within Pakistan.
