WASHINGTON - More than half of Muslim-Americans in a new poll say that government anti-terrorism policies single them out for increased surveillance and monitoring, and many report increased cases of name-calling, threats and harassment by airport security, law enforcement officers and others.

Still, most Muslim-Americans say they are satisfied with the way things are going in the US and rate their communities highly as places to live.

The survey by the Pew Research Center, one of the most exhaustive ever of the country's Muslims, finds no signs of rising alienation or anger among Muslim-Americans despite recent United States government concerns about homegrown Islamic terrorism and controversy over the building of mosques.

"This confirms what we've said all along: American Muslims are well integrated and happy, but with a kind of lingering sense of being besieged by growing anti-Muslim sentiment in our society," said Ibrahim Hooper, spokesman for the Council on American-Islamic Relations, a Washington, DC-based Muslim civil rights group.

"People contact us every day about concerns they've had, particularly with law enforcement authorities in this post 9/11 era," he said.

Muslim extremists hijacked the planes on Sept 11, 2001, crashing them into the New York's World Trade Center, the Defense Department near Washington and a field in Shanksville, Peensylvania.

In all, 52 percent of Muslim-Americans surveyed said their group is singled out by government for terrorist surveillance. Almost as many - 43 percent - reported they had personally experienced harassment in the past year, according to the poll released Tuesday.

That 43 percent share of people reporting harassment is up from 40 percent in 2007, the first time Pew polled Muslim-Americans.

Asked to identify in what ways they felt bias, about 28 percent said they had been treated or viewed with suspicion by people, while 22 percent said they were called offensive names.
