New York (CNN) -- Authorities have arrested a man they claim was plotting to detonate pipe bombs in and around New York, Mayor Michael Bloomberg said Sunday night. The intended targets of Jose Pimentel, 27, were U.S. military personnel who had served in Iraq and Afghanistan, as well as U.S. postal facilities and police in New York and Bayonne, New Jersey, according to Bloomberg and New York Police Commissioner Ray Kelly. The suspect was described by Bloomberg as an "al Qaeda sympathizer," though he is not believed to have ever worked with or received training from anyone in that terrorist organization.

"We knew for the last two years, he's been reading a lot of jihadist information and talked a lot of inflammatory rhetoric," Kelly said of
Jose Pimentel.
