The security plan in place for the London Marathon this weekend will be reviewed following the deadly bomb blasts in Boston, London's Metropolitan Police said Tuesday.

"We will be reviewing our security arrangements in partnership with London Marathon," said event commander Chief Supt. Julia Pendry.

Police and race organizers said they are working closely together on security arrangements for Sunday's race, which attracts tens of thousands of competitors and spectators each year.

The organizers of the London Marathon said they expected the event "will go ahead as originally scheduled."
