NEW YORK - The Committee to Protect Journalists, an independent watchdog, has urged President Asif Ali Zardari to ensure the safety of journalists in Pakistan, citing two recent incidents. A CPJ press release issued Friday expressed concern over the attack on journalist Imtiaz Alam by a gang in Lahore that resulted in injuries to him and the bombing of the building housing the Wana Press Club in South Waziristan. "There is growing concern for the safety of journalists in Pakistan amid a surge in attacks apparently by militant groups who cannot abide critical reporting. President Asif Ali Zardari must act swiftly to assert the government's authority and reverse this trend," Bob Dietz, CPJ's Asia program coordinator, said.
