Canada has banned Irish language band Kneecap from entering the country, saying the group has "made statements that are contrary to Canadian values" that "have caused deep alarm".
The hip-hop trio was due to perform in Toronto at two shows in October, and at two others in Vancouver.
Canadian officials cited terror offence charges brought against one member of the group, Liam Óg Ó hAnnaidh, in the UK in May, after he allegedly displayed a flag in support of the Lebanese militant group Hezbollah - which the UK considers a terrorist organisation - at a London gig last year.
The 27-year-old denies the charges, with Kneecap calling the Canadian ban "deeply malicious" and threatening legal action.
Announcing the ban on Monday, Canadian Liberal MP and Parliamentary Secretary for Combating Crime Vince Gasparro said in a video on X the group has "amplified political violence and publicly displayed support for terrorist organisations such as Hezbollah and Hamas."
