NEW YORK (AP) - Hundreds of family members of Sept. 11 victims recited loved ones' names through tears on the ninth anniversary of the attacks Saturday, avoiding direct mention of the political furor over plans for a mosque that later drew thousands of protesters on both sides.
After the ceremony, around 1,000 activists rallied about five blocks from the site of the 2001 attacks to support the proposed Islamic community center. Several hundred others rallied nearby, chanting "USA, USA" and "No mosque here."
Speaking at the Pentagon, President Barack Obama alluded to the controversy over the mosque - and a Florida pastor's threat, later rescinded, to burn copies of the Quran. Obama made it clear that the U.S. is not at war with Islam and called the al-Qaida attackers "a sorry band of men" who perverted religion.
"We will not give in to their hatred," Obama said. "As Americans, we will not or ever be at war with Islam."
Family members at observances in New York and Pennsylvania brought flowers, pictures of loved ones and American flags. Reading victims' names along with architects and construction workersrebuilding at ground zero in New York, they urged a restrained tone.
"Let today never, ever be a national holiday. Let it not be a celebration," said Karen Carroll, who lost her brother, firefighter Thomas Kuveikis. "It's a day to be somber; it's a day to reflect on all those thousands of people that died for us in the United States."
A diverse crowd of pro-mosque activists lined two blocks next to City Hall chanting "Hey hey, ho ho, racism has got to go," before marching to an area near ground zero.
Elizabeth Meehan, a 51-year-old Christian from Saratoga, N.Y., rode in by bus from her home 180 miles away.
"I'm really fearful of all of the hate that's going on in our country. People in one brand of Christianity are coming out against other faiths, and I find that so sad," she said. "Muslims are fellow Americans; they should have the right to worship in America just like anyone else."
The event was largely peaceful, except for occasional exchanges with anti-mosque passers-by.
One man walked by holding a poster that said, "Stop Obama's Mosque," while another held a more provocative sign with a Quran attached.
At the anti-mosque rally nearby, some participants wore clothing featuring stars and stripes, and some carried signs with messages including "It stops here" and "Never forgive, never forget, no WTC mosque."
"My grandparents didn't expect special treatment. They didn't fly planes into buildings," said Theresa Angelo, 57, of the New York City borough of Queens. "No other culture does that. This is hallowed ground. It's something like Gettysburg or Pearl Harbor.
Why did they have to do it here? Be a little sensitive." At the anniversary ceremony, stifling sobs in front of microphones, some Sept. 11 family members who read names sought to emphasize sentiments on all sides of the mosque argument.
Some - like Elizabeth Mathers, whose father, Charles Mathers, worked at Marsh & McLennan at the trade center - stressed that ground zero is hallowed.
"New York, please be mindful this is a sacred site and should be respected as such," she said.
Many sought to embrace unity and a spirit of reaching out, which is what the developers of the Islamic center have said is their goal.
"May we share your courage as we build bridges with other people to prevent this from happening again and to preserve human dignity for all," said Robert Ferris, saluting the dozens of building workers who joined families in reading names.
Ferris lost his father, who worked at Aon Corp. Bagpipes and drums played to open the ceremony. Mayor Michael Bloomberg spoke briefly of the 2001 attack: "No other public tragedy has cut our city so deeply. No other place is as filled with our compassion, our love and our solidarity."
Moments of silence were held at 8:46 a.m., 9:03 a.m., 9:59 a.m. and 10:28 a.m. to mark the times the hijacked jetliners hit the north and south towers of the World Trade Center, as well as the times they collapsed.
Hundreds of family members later placed roses in a reflecting pool at ground zero in front of a memorial, leaving scrawled remembrances on paper around it. Visible behind the podium of mourners were the beginnings of two skyscrapers rising at the site along with a transit hub.
Laura Bush, first lady at the time of the attacks, joined current first lady Michelle Obama at a service in Shanksville, Pa., for victims of the flight that crashed in a field there, while the president attended the service at the Pentagon.
"May the memory of those who gave their lives here continue to be an inspiration to you and an inspiration to all of America," Michelle Obama said, thanking Bush for helping the country through the aftermath of Sept. 11.
The mosque debate pits advocates of religious freedom against critics who say putting an Islamic center so close to ground zero disrespects the dead.
A Florida pastor's threat to burn copies of the Quran, which inflamed much of the Muslim world and drew a stern rebuke from Obama, was called off on Saturday.
"We feel that God is telling us to stop," Terry Jones said on NBC's "Today" show after flying to New York. Pressed on whether his church would ever burn the Islamic holy book, he said: "Not today, not ever. We're not going to go back and do it. It is totally canceled."
Protests continued Saturday in Afghanistan. Police fired warning shots to prevent protesters from storming the governor's residence in Puli Alam in Logar province, officials said. Villagers set fire to tires and briefly blocked a highway to Pakistan, a provincial spokesman said.
Vice President Joe Biden spoke at the New York ceremony, where 2,752 people were killed when two jetliners flew into the trade center. Forty people died in Pennsylvania and 189 at the Pentagon.
