WASHINGTON -- A House committee will hold a hearing next week on the bombing at the Boston Marathon that killed three and wounded more than 200 others.

Boston Police Commissioner Ed Davis is among those invited to testify at the hearing, to be held on May 9 by the House Homeland Security Committee.

The panel's chairman, Texas Republican Rep. Michael McCaul, says the session will be the first in a series of hearings looking at the ways federal, state and local officials communicated with their counterparts at other agencies regarding the bombing suspects before and following the event.

McCaul says the marathon bombing was an attack by radical Islamist terrorists.
