YEREVAN, SEPTEMBER 10, ARMENPRESS: U.S. Representative John Sarbanes is concerned over Safarov release, reports Armenpress citing ANCA. ''The pardoning of Ramil Safarov, the murderer of Gurgen Margaryan, is without justification. The basis and reasoning for his transfer to Azerbaijan must be explained to the United States. Azerbaijan has acted to undermine justice and further strain its relationship with Armenia to the detriment of all, and to the benefit of no one but a self confessed murderer. Azerbaijan's contemptible granting of amnesty to Safarov undermines the international community's efforts to forge a peace in the Caucuses'', stated Sarbanes.
