The Latest on false reports of a shooter that led to evacuations at Los Angeles airport (all times local):

7:10 a.m.

Operations are returning to normal at Los Angeles International Airport after false reports of a gunman caused panicked evacuations, but flights have seen major delays.

Airport spokeswoman Nancy Castles said Monday that about 280 flights were delayed, including 120 arrivals and 161 departures. At least 27 flights were diverted to other airports, and two were canceled.

Castles says traffic on the upper departure level flowed smoothly during morning rush hour, but cars backed up on the lower arrival level.

Los Angeles police spokesman Andy Neiman said a search Sunday through the terminals uncovered no evidence of a gunman or shots fired. Loud noises spurred the reports, and police are still investigating to find the source of them.
