TEHRAN (Agencies)- Iran's Police Chief Brigadier General Esmaeil Ahmadi Moqaddam has voiced preparedness of his troops to trace and haunt militants who escape to Pakistan after staging operations in the Islamic Republic. Speaking in an interview with Farse News Agency (FNA) here on Saturday, the Iranian police chief expressed his regret over the weak performance of the Pakistani border police in confronting terrorists, and said, "We are not witnessing any practical move" by the Pakistani border guard in harnessing terrorists' border crossing. "...if they (Pakistan) are incapable of facing militants we are ready and have the power to seriously encounter terror groups inside Pakistani soil," he added. Ahmadi Moqaddam also called on the Iranian foreign ministry to play a proactive role in resolving the issue. Reminding recent crimes by terrorist groups in eastern Iran, the General announced that there exists corroborative evidence to prove that such terrorist groups are supported by alien intelligence services. In a recent development, a sound bomb exploded in Al-Ghadir mosque in the city of Zahedan, southeastern Iran near Pakistan on Wednesday, causing minor damage but no casualties. "These blind acts aim to put Iran under pressure," the Iranian police commander added. Earlier in January, a senior Iranian judiciary official said that Iran has documents to prove the United States and Britain back a group that killed 16 abducted Iranian police officers. The terrorist group Jundollah this month killed 16 police hostages who were abducted from a checkpoint in the southeastern Sistan-Baluchestan province in June. Iranian officials say that Jundollah's head, Abdolmalek Rigi, is part of the Al-Qaeda network. "There are documents that show that Britain and America are supporting Rigi's terrorist group with arms and information," First Deputy Judiciary Chief Ebrahim Raisi said.
