Yesterday’s terrorist attack on the Boston Marathon will have long-term ramifications for more than just U.S.-based sporting events.

Future international sporting events will likely see more stringent precautions to keep both athletes and spectators safe. 

Russian authorities have promised tougher security measures at August’s world athletics championships after explosions near the finish line of the Boston marathon killed three people and wounded more than 100.

“The security arrangements will certainly be reviewed after what happened in Boston,” Russia’s athletics chief Valentin Balakhnichyov told Reuters on Tuesday.

“Security has always been of the highest standard at all our sporting events but, no doubt, we will take into account the latest events and how it was done.”
