Offices in Capitol Hill received a manila envelope with a letter claiming responsibility for today's bombing of a landmark military recruiting station in Times Square, NYC. Our parent site, Gothamist, tells us that "WNBC reports that the letters, which arrived today, included a photo of the Army recruiting center 'before it was bombed and...the words 'We did it.'" Which group is claiming responsibility, exactly, remains to be known.

According to the AP, Senator Dianne Feinstein's office sent the following email to other lawmakers:

"A few offices on the House side have received a letter today addressed to 'Members of Congress' with a picture of a man standing in front of the Times Square recruiting station that was bombed in New York today with the statement 'We did it.' He is standing in front of it with his arms spread out and he's attached his political manifesto."

The email, according to Gothamist, also advised people not to open the letters and contact the police.

Today's Times Square attack caused minimal damage to a "New York military recruiting station before dawn Thursday and police were searching for a hooded bicyclist seen on a surveillance video pedaling away," according to CBS. Although the blast was minor, it could have caused "injury and even death."
