We should put pressure on the US to extradite former Central Bank Governor Abdul Qadir Fitrat back to Afghanistan, President Hamid Karzai said in a meeting with Afghan lawmakers Thursday.
He also called on Afghan parliamentarians and the international community to do more to stump out corruption.
Addressing to both houses of parliament and the judiciary, Mr Karzai added that unity was needed to tackle the current challenges Afghanistan is facing.
He cited corruption as a major challenged despite ten years of efforts.
Mr Fetrat quit in June 2011 claiming he was under threat for investigating fraud at the privately-owned Kabul Bank.
The government condemned his decision, adding that he himself was under investigation for fraud.
Mr Fetrat claimed the government had interfered in his efforts to pursue those responsible for corruption at the Kabul Bank, which almost collapsed in 2010 after evidence of large-scale embezzlement emerged.
