From a security monitor inside his office, Oumer Wako can watch the progress as a warehouse along Minnehaha Avenue is converted into the Tawfiq Islamic Center's new mosque, an expansion more than 10 years in the making.
But on a trip to the mailbox last fall, Wako discovered that the mosque where he is executive director had become a target of hate as well as pride.
"To whome [sic] it may concern: I will blow up your building with all you immigrants in it just like you blew up our iconic building in New York in 2001," began the anonymous note, written in a messy scrawl. It concluded: "Get the [expletive] out is a suggestion to you."
The letter, written by a man who lived nearby and is now in federal custody, was the latest in a surge of hate crimes against Muslims, both in Minnesota and nationally, to levels not seen since the aftermath of 9/11.
While alleged terrorist acts by American Muslims dominate public debate, terror acts against Muslims are rising sharply, even as other hate crime categories appear to be on the decline, according to researchers and data reviewed by the Star Tribune.
The incidents have alarmed Twin Cities Muslims, though many say they are uncertain whether to notify law enforcement or respond quietly for fear of fanning more hostility.
Federal law enforcement officials have taken notice, stepping up public appearances this month in an effort to encourage more reporting of such crimes.
"You never want to wake up one day having not taken action," U.S. Attorney Andrew Luger said at a community forum on hate crimes last week. "We need to know what's going on so we can be responsive to you."
