Flights are gradually resuming after being grounded for about two hours Sunday night at the Winnipeg James Richardson International Airport, according to spokesperson for the Winnipeg Airports Authority.

Outbound flights began taking off again at about 6:50 but many flights will continue to be delayed because of the long queue of planes waiting to take off, said the spokesperson.

Baggage drop areas at the Winnipeg airport have also returned to normal after being shut down earlier Sunday due to the security investigation.

A total of 12 outgoing flights were affected by a "security incident" involving baggage at the airport Sunday afternoon.

No flights were cancelled.

An investigation is still ongoing into Sunday's security incident. (CBC) Few details have been provided about the incident except that the investigation is still ongoing, said the spokesperson.
