A performer at Kendrick Lamar’s Super Bowl halftime show unfurled a flag emblazoned with the words Sudan and Gaza in a protest over the two wars that are roiling the Middle East. Security at the stadium detained the performer shortly after waving the flag atop a car used as a prop in the performance.

The Super Bowl halftime performer who unfurled Sudanese and Palestinian flags in an apparent protest action in New Orleans Sunday night will be banned for life from all NFL stadiums and events, an NFL spokesperson told CNN.

No one involved with the production was aware of the individual’s intent,” the N.F.L. said in a statement about the protest during Kendrick Lamar’s show.
