WASHINGTON (AFP) - US officials charged two suspected Pakistani agents Tuesday over an alleged decades-long effort that funnelled millions of dollars to Washington to lobby the Kashmiri cause in the corridors of power. The Justice Department unsealed conspiracy charges against Ghulam Nabi Fai, 62, a US citizen, and Zaheer Ahmad, 63, a US citizen and resident of Pakistan, and said both men faced five years in prison if found guilty. Foreign governments who try to influence the United States by using unregistered agents threaten our national security, said FBI Assistant Director in Charge James McJunkin. Under the Foreign Agents Registration Act, it is illegal for agents of foreign governments to seek to influence US policy or law without fully disclosing their identity and any underlying information. Fai was arrested on Tuesday morning and set to appear Thursday before a court in Alexandria, near the US capital. Ahmad was believed to be in Pakistan. Mr Fai is not a Pakistani citizen and the government and embassy of Pakistan have no knowledge of the case involving him, a spokesman from the Pakistani embassy told AFP. The influence peddling allegations, which come amid increasingly strained ties between the United States and Pakistan, centre on the Kashmiri American Council (KAC), a Washington-based NGO founded in 1990. According to the affidavit, Fai and the KAC have received at least $4 million from the Pakistani government since the mid-1990s through Ahmad and his funding network, the Justice Department said. The complaint said KAC was one of three Kashmir Centers actually run by Pakistans military intelligence service, the Inter-Services Intelligence Agency (ISI) the other two being in London and Brussels. Fai, who serves as KACs Washington director, is accused of using money provided by Ahmad to lobby politicians and their aides in Washington to support Pakistans desire for self-determination for Kashmiris.
