Iraq's parliament on Saturday discussed a motion condemning Turkey for threatening an incursion to crack down on Kurdish rebels as Baghdad and Ankara were said to be considering a joint operation.Lawmakers failed to agree on the wording of the motion that would condemn Turkey's parliament for authorising its military to cross the mountainous border to hunt down rebels of the Kurdistan Workers' Party (PKK). "The Iraqi parliament did not reach a final formula for the draft statement presented by the parliament presidency committee," speaker Mahmud al-Mashhadani said.
