But it said the project, championed by little-known Florida preacher Terry Jones, was among "instances of intolerance, discrimination, profiling and acts of violence against Muslims occurring in many parts of the world."

The move came amid increasing efforts by the OIC -- which has Russia, China and Asian and African states as allies in the council -- to have the U.N. recognize "Islamophobia" as racism and open to challenge under international law.

It also follows widespread demonstrations around the Muslim world in which a number of anti-U.S. protesters have been killed even after Jones withdrew his proposal to stage the burning on September 11, the ninth anniversary of the hijacking attacks in New York and Washington.

In speeches in Geneva over the past few days, OIC secretary-general Ekmeleddin Ihsanoglu of Turkey has also argued that Jones' plan underscored his grouping's long-standing demands for a U.N.- backed ban on "defamation of religion".

Western countries and some allies in Latin America oppose both the OIC efforts, arguing that they undermine freedom of expression and freedom to discuss openly religion-based practices that infringe universal human rights.

Last week, a Pakistani-born Canadian Muslim academic, Raheel Raza, told the council, whose members include Libya and Saudi Arabia, that OIC countries systematically abuse the rights of everyone living on their territory, especially women.

European diplomats said they were unlikely to vote against the OIC resolution, as their governments had already condemned the Quran burning idea, but feared it would be used to increase pressure for actions on defamation and "Islamophobia."

The resolution, together with others yet to be submitted at the council, is likely to be voted on when the body wraps up its current autumn session at the end of next week.

Muslim groups back Islamic center near ground zero

Leaders of prominent U.S. Muslim groups called Monday for a national week of interfaith dialogue to combat religious intolerance and said they support the right to build a controversial Islamic center near ground zero.

"We stand for the constitutional right of Muslims, and Americans of all faiths, to build houses of worship anywhere in our nation as allowed by local laws and regulations," the Muslim leaders said in a statement delivered at the site of the proposed Islamic center and mosque, to be called Park51.

They called for a "week of dialogue" on the weekend of Oct. 22-24, during which Muslims would conduct open houses at their places of worship to help ease tensions.

"We ask Muslims to open mosques nationwide to welcome people, to let them understand the Islamic faith and what American Muslim community is," said Nihad Awad, national executive director of the Council on Islamic-American Relations. "We also urge Muslims to visit places of worship in other faith communities."

The Muslim leaders spoke after a daylong summit meeting Sunday at a hotel near Kennedy Airport.

The 20 groups participating in the summit included the Council on Islamic-American Relations and the Islamic Society of North America, the two best-known U.S. Muslim groups, as well as the Islamic Circle of North America and the Muslim Alliance in North America.

Neither the developer of the Islamic center nor its imam attended the news conference, though developer Sharif El-Gamal attended the summit. Imam Feisal Abdul Rauf Rauf welcomed the Muslim leaders' support in a statement.

"I welcome the support of the Islamic Leadership Council for the Cordoba Initiative's plans to proceed with a community center in lower Manhattan, which has attracted such broad national and global attention," Rauf said. "On a day when American Muslim leaders stand strongly in favor of protecting civil rights, and denouncing bigotry in all forms, it is important to remember that world-wide efforts to foster peace must begin in our home communities."

He added, "We must insist on going forward with causes that we know will further peace between all peoples."

The developers said in a separate statement, "The leaders of Park51 are grateful to the over 100 Muslim American leaders and their organizations who announced their support today of the Islamic community center being built in Lower Manhattan. Our community remains committed to building bridges of understanding to our neighborhoods, to our city and to the rest of America."

Summit organizers said Rauf did not attend Sunday because of security concerns.

Park51's proposed location two blocks from the World Trade Center site has upset some relatives of Sept. 11 victims and led to angry demands that it be moved. Critics say the site of mass murder by Islamic extremists is no place for an Islamic institution.

Republicans including Sarah Palin and Newt Gingrich have denounced plans for the mosque, and a Florida pastor threatened to burn copies of the Quran because of it.

The Muslim leaders who spoke Monday did not address proposals to move the mosque to a less sensitive location.

They called on elected officials "to join their colleagues in denouncing and rejecting inflammatory rhetoric that endangers the lives of Muslim Americans."

While the leaders said they supported the mosque, none promised financial backing.

Ihsan Bagby, an associate professor of Islamic studies at the University of Kentucky, said the organizations' support would facilitate fundraising for the project.

"The summit has underlined the support of the major national Muslim organizations for the Park51 project," Bagby said. "And in doing so they have opened the door for fundraising in the American Muslim community."

Participants at the news conference refused to answer a question about whether they would denounce Hamas, the militant Palestinian group that that United States considers a terrorist organization.
