Fans attending Major League Soccer games will be subjected to screenings and bag checks as part of beefed-up security measures, the league said Tuesday.

A range of enhanced security measures will be rolled out at matches throughout the United States from this weekend in an effort to bring the MLS into line with other sports.

"Under the new security policy, all guests will be fully screened upon entry into MLS venues," a statement said.

"The screenings will be conducted via a full pat down or with the use of a search wand of magnetometers."

The new measures will also see fans banned from bringing large purses, coolers, briefcases, backpacks, computer bags, camera bags or luggage into venues.

"Public safety is a top priority and the enhanced security measures will ensure that fans are able to continue to enjoy MLS and SUM events in a safe environment," said MLS president and deputy commissioner Mark Abbott.

"The safety of our fans, players and staff is paramount," added Ray Whitworth, senior VP of security and operations.

"The updated security measures bring us in line with professional sports leagues around the United States and Canada while maintaining the unique sports experience that is MLS."

The security measures will be in effect at all 20 MLS venues from April 23.
