June 14 (Reuters) - Canada's WestJet Airlines is

investigating a cybersecurity incident that has disrupted access

to its mobile app and some internal systems, affecting an

undisclosed number of users, the airlines said in a statement on

Friday.

WestJet said specialised internal teams are working

alongside law enforcement and Transport Canada to limit the

impact and determine the scope of the breach.

"We are expediting efforts to maintain the safety of our

operation and safeguard sensitive data and personal information

for both our guests and employees," the statement said.

The carrier added that it is too early to speculate on

further details or the potential scope of the incident.

WestJet did not immediately respond to a request for

comment.

Canada's critical infrastructure has seen a rise in cyber

threats. Earlier in April, energy provider Emera ( EMA ) and its

subsidiary Nova Scotia Power disclosed a cyber intrusion that

involved unauthorized access to parts of their network and

business servers.
