Tension between Sunnis, Shiites emerging in USA

"For years, Sunnis and Shiites in this country have worked together to build mosques, support charities, register voters and hold massive feasts for Eid al-Fitr (on Oct. 13 this year in the USA), the celebration at the end of the holy month of Ramadan.
Now there are small signs of tension emerging in America's Muslim community that are raising concerns among many of its leaders. They worry that the bitter divisions that have caused so much bloodshed abroad are beginning to have an impact here. Such concerns are rising at a time when the USA's Muslim community has grown from less than 1 million in 1990 to nearly 2.5 million today, with two of three Muslims born overseas, according to a survey by the Pew Research Center.
"You have people who recently arrived from other places where things may have gotten out of hand," says Sheik Hamza Yusuf, the U.S.-born co-founder of the nation's first Muslim seminary, the Zaytuna Institute, in Berkeley, Calif. "It takes just one deranged person with a cousin back home who died in a suicide bombing to create trouble here."
