MADRID (AP) -- Spanish authorities are increasing security for the Madrid Marathon following the deadly bombings in Boston.

Regional government spokeswoman Cristina Cifuentes and city security official Jose Enrique Nunez say 1,100 police and security personnel will be on duty for Sunday's race.

The security force will include 400 National Police officers, as well as a rapid reaction and prevention force, dogs and motorcycles. Cifuentes says "we have not detected a risk, but understand that at the present time it is important that National Police reinforcement should participate."

Three people were killed and more than 180 injured when two bombs exploded near the finish line of last week's Boston Marathon.
