The Circuit of The Americas has announced the security measures in place for this weekend's inaugural MotoGP event in Austin, Texas.

All guests will be required to go through security checkpoints prior to entering the venue, with 'all bags, purses, backpacks and persons subject to screening by security personnel'.

The circuit statement added that such measures are normal for major events and were utilised during last November's F1 Grand Prix.

But in the wake of this week's tragic attack on a major US sporting event, the Boston Marathon: "We have been in touch with local law enforcement following yesterday's unfortunate events in Boston, Mass., and will work with them throughout the upcoming weekend to ensure we conduct a safe and secure event," said Circuit vice president of Public & Media Relations Julie Loignon.
