Canadian police foiled a Valentine's Day plot by two suspects who were planning to go to a shopping centre and kill as many people as they could before committing suicide.

Police acted quickly after receiving information about the intended attack in Halifax from the public on the Crime Stoppers tip line. A 19-year-old male suspect shot himself dead after police surrounded his home,while a 23-year-old woman was arrested at Halifax airport

Police said the suspects used a chat stream and were apparently obsessed with death and had many photos of mass killings. Officials said the plot was not related to Islamic terrorism.
