The Oklahoma Highway Patrol says there have been no threats or heightened security in the aftermath of a bombing at the Boston Marathon - but that senses are heightened.

Oklahoma City Mayor Mick Cornett says there are currently no plans to call off this year's Oklahoma City Memorial Marathon - but said events will be monitored daily.

"Obviously this time of the year on the calendar is a heightened alert in Oklahoma City. It has been for 18 years," Cornett says, referencing the 1995 bombing of the Alfred P. Murrah Federal Building.
