Three people are thought to have died in Glasgow in the second mass stabbing attack in Britain in less than a week.
Police shot dead the male suspect at the scene of the incident, which occured shortly after lunchtime on Friday at the Park Inn hotel.
A police officer who was also stabbed during the attack has been rushed to hospital.
The Scottish Police Federation tweeted: “We appreciate families of police officers in Glasgow will be anxious to hear that a police officer has been stabbed.
“Please be aware the family of the officer has been notified and is being supported by the service.”
Streets in central Glasgow have been sealed off and heavily armed police are on the scene.
Medias reported three people had died during the incident however that has not been confirmed by police.
In a statement, Scotland Police said the situation was contained “and there is no danger to the general public”.
“Armed police officers attended the incident and I can confirm that a male suspect was shot by an armed officer,” said assistant chief constable Steve Johnson.
“I would like to reassure the public that at this time we are not looking for anyone else in relation to this incident. I can also confirm that a police officer was injured while dealing with the incident and that officer is receiving treatment in hospital.”
Three people were killed and three others injured during a mass stabbing in the English town of Reading last Saturday which police have declared a terrorist incident.
