BAGHDAD, March 29 (Xinhuanet) -- The second session of Iraq's newly sworn-in National Assembly opened Tuesday, after last-minute talks over who will be nominated for the speakership failed to achieve results.

    Dhari al-Feiyadh, the acting president of the parliament, told lawmakers that he expected the Sunni Arab politicians will nominate a candidate for the post of speaker on Sunday.

    Minutes after the session opened, journalists were told to leave the scene as Feiyadh said the lawmakers were to "start close-door discussion about internal regulations of the National Assembly."

    Tuesday's assembly is the second in two months after hundreds of thousands of Iraqis defied insurgent threats and continued violence to vote in the polling stations on Jan. 30.

    A speaker and two deputies were expected to be agreed upon at the meeting.

    Earlier on Monday, outgoing Interim President Ghazi al-Yawar refused to accept the post of parliament speaker, asking to be oneof two vice presidents instead.

    After a delay of two and half hours, the meeting started mid-Tuesday with complaints by legislators about the behind-the-scene negotiations over the key cabinet posts.

    The formation of a new Iraqi government is still kept in limbo due to political haggling between various blocs on who gets what post.

    The United Iraqi Alliance was the biggest winner in the elections, securing 140 seats, and the Kurdish bloc garnered 75 seats. While Sunnis, about 20 percent of the Iraqi population, arepoorly represented since most of them boycotted the vote due to anger or fear for retaliation.

    At least two explosions reverberated across central Baghdad at the time of the session, taking place inside the heavily fortifiedGreen Zone on the western bank of the Tigris River.

    There was no report of casualties or damage after the blasts, apparently caused by a mortar attack. Enditem
