Baghdad, July 9 (IANS) Iraqi Prime Minister Nuri al-Maliki Wednesday accused the Kurds of providing a base for the operations of terrorist groups, promising to free all lands seized by the militants. "We will never be silent that Arbil become a base of operation for Daash (Arabic first letters of the Islamic State in Iraq and Greater Syria or ISIs), Baath, Al Qaeda and other terrorists," Maliki said in his weekly televised speech. Maliki called on the authorities of Arbil, the capital of the semi-auto**mous region of Kurdistan, to stop the activities of opposition politicians and some political figures of Sunni insurgent groups, Xinhua reported. For years, the Shia Iraqi prime minister has been at odds with the Kurds, and relations between the central government in Baghdad and authorities in Kurdistan further deteriorated after Sunni insurgents took control of several provinces adjacent to the Kurdish region.
