NEW ORLEANS — A performer who was part of Kendrick Lamar’s Super Bowl halftime show was detained by security after waving the Sudanese flag and Palestinian flag together with the words “Sudan” and “Gaza” written on them toward the end of the performance, the NFL said.

The man was an entertainer during Kendrick Lamar’s performance, but his demonstration was not part of the script, the NFL said.

As Kendrick Lamar performs in the background, a man is seen in video running onto the field and unfurling a Palistinian flag.
