Poor checks on carry-on baggage between Wellington and Christchurch airports has raised concerns that others potentially involved in Friday’s terrorist attack in New Zealand could slip out of the city. At least 49 people have been killed and more than 20 others have been seriously injured in the wake of shootings at two Christchurch mosques. Authorities have arrested three men and one woman over the shootings, but New Zealand Police has not ruled out the possibility that more attackers could be at large. Sky News reporter Jackson Willians was able to fly from Wellington to Christchurch without a single item of carry-on luggage being screened. Air New Zealand has cancelled all turboprop flights out of Christchurch scheduled for Friday evening.
