Turkey's prime minister on Friday said Israel should be barred from the United Nations while it ignores the body's calls to stop fighting in Gaza. "How is such a country, which does not implement resolutions of the UN Security Council, allowed to enter through the gates of the UN (headquarters)?" Recep Tayyip Erdogan said. Erdogan spoke before UN Secretary General Ban Ki-moon arrives in Ankara to discuss the conflict. His comments reflected a growing anger in Turkey, Israel's best friend in the Muslim world, over Israel's Gaza operation. Erdogan accused Israel of attacking civilians under the pretext of targeting Islamic militant group of Hamas. President Abdullah Gul on Friday renewed calls for an immediate cease-fire and also urged US President-elect Barack Obama to focus on a comprehensive, long-lasting and fair solution once in office.
