Fall classes began September at Colby, but without Zafaryab Ahmed, a Pakistani journalist who is supposed to be the inaugural recipient of the College's Oak Human Rights Fellowship. As of September 16, Ahmed remained in Pakistan, barred by his government from traveling. Charged with sedition after writing about the exploitation of children in Pakistani factories, he was awaiting a court ruling on whether he would be allowed to travel to the U.S. to fulfill the one-semester fellowship.     The Committee to Protect Journalists (CPJ), a nonpartisan organization of journalists dedicated to the defense of their colleagues around the world, renewed its campaign to secure for Ahmed what it called "the fundamental right to travel freely."     A letter sent by CPJ Executive Director Ann K. Cooper to Pakistan's Prime Minister, Muhammad Nawaz Sharif in Islamabad, said, "the CPJ is deeply troubled by the prolonged persecution of Ahmed on the basis that his reporting was a threat to national security. We are further disturbed by the failure of the justice system to respond to Ahmed's petitions."     Ahmed was barred from leaving the country following his arrest in 1995 on charges of sedition that were leveled after he wrote about child labor in Pakistan and about the murder of Iqbal Masih, a 12-year-old who helped expose working conditions.     After many delays, Ahmed finally had a hearing in a Pakastani courtroom in Lahore September 4, according to Professor of Government Kenneth A. Rodman, director of the Oak Institute for the Study of International Human Rights, but as of September 16 there was still no word on Ahmed's fate.     Rodman said the CPJ initiative on Ahmed's behalf adds to pressure being applied through political, diplomatic and non-governmental channels. Amnesty International and the CPJ both initially took up Ahmed's case in 1995.     In the past few weeks Rodman and Oak Institute Associate Director Eliza Denoeux solicited help from Maine's Congressional delegation, the State Department's Pakistan desk, the U.S. Information Agency and the U.S. Embassy in Lahore. Denoeux also appealed to Pakistan's embassy in Washington, urging officials there to help secure Ahmed's freedom to travel.
