BAGHDAD, Oct. 11 (Xinhuanet) -- Iraqi leaders agreed on Tuesday to review possible changes to the constitution after the country's December elections in order to get Sunni Arabs' support in a weekend referendum of the charter, officials said.   

 A spokesman for Iraqi President Jalal Talabani revealed that Shiite, Kurdish and Sunni leaders had reached a basic agreement to amend the constitution.

    However, negotiations are still going on among the leaders to decide on which articles of the constitution would be reviewed, he added.

    According to the spokesman, an announcement about the details of changing the constitution will be released on Wednesday.  

 Meanwhile, a senior member of Prime Minister Ibrahim Jaafari's Dawa Party also confirmed that an accord has been reached on amending the constitution and a committee will be set up after the December parliamentary elections to come up with possible changesto the charter within four months after its creation. 

  Sources concerned said the US diplomats had played an important role in bringing Iraqi leaders to reach the agreement, which isseen as an attempt by the Shiite-Kurd dominated government to win Sunni Arabs' endorsement of the constitution, which is to be put to a national referendum on Saturday.

    Many Sunni leaders have called upon the community, making up a fifth of Iraq's population, to vote "No" to the charter or boycott the ballot. They say the constitution will marginalize the Sunnisand plunge the country into sectarian strife.

    But Ayad Sammarai, spokesman for the Iraqi Islamic Party, the main Sunni Arab party, announced that "there was an agreement and we are calling for a 'yes' vote."

    The constitution will be vetoed if two thirds of the voters in at least three provinces say "No" to it.  Enditem
