ARLINGTON, Va. (AP) - Arlington National Cemetery will increase its security measures, including requiring a government-issued photo ID for people arriving in cars and screening pedestrian visitors.

Cemetery spokeswoman Jennifer Lynch said in an email Monday that the measures will be phased in starting in November.

Visitors will also have their bags searched before entering the cemetery. The screenings will be very similar to what is already done at D.C. museums.

Officials say this is all meant to help keep visitors safe and increase security measures.

Somewhere between three to four million people visit the cemetery each year. This could potentially cause some delays for people visiting. Build in some extra time if you are in a large group.
