Hundreds of worshippers, many in traditional garb, then marched several blocks to a police precinct, some carrying American flags and others placards reading ''Bin Laden out of Afghanistan'' and ''Terrorism is against Islam.''

Many said they favor U.S. military action in their homeland.

''We hope America will make our country free,'' said Zabi Rustami, 40, a wholesale food salesman who fled Afghanistan more than a decade ago. ''I'm worried for my family there, but you have to sacrifice something.''

About one-quarter of New York's estimated 20,000 Afghan immigrants pray at the mosque, Masjid Hazrat-I-Abubaker Sadiq, which is tucked into a leafy residential neighborhood.

The mosque, which had an American flag posted on one of its front windows, lost one of its own in the terrorist attacks on the World Trade Center on Sept. 11.

Photos of Salman Hamdani, an emergency medical technician who is missing and presumed dead, hung in the mosque's stairwell under a prayer written in Arabic and English: ''Oh Allah I am asking your grace.''

Some of the women wept during the sermon when the imam spoke of the impoverished Afghan people. He described them as victims of the ruling Taliban, and blamed the group's rise to power on the leadership of Pakistan and on Arab extremists.
