Fans of the Irish-language hip-hop group Kneecap have mobbed sidewalks outside a London court as a member of the trio faced a terror-related charge in what he says is a politically motivated effort to silence the band’s support for Palestinians before its appearance at the Glastonbury Festival.

Kneecap ’s Mo Chara appeared at Westminster’s Magistrates Court on Wednesday (June 18) in relation to an alleged terror offense.

Last month British Police confirmed that Liam Óg Ó hAnnaidh, whose stage name is Mo Chara, was charged with a terrorism offence. He is alleged to have displayed of a flag in support of Hezbollah at a gig at the O2 Forum in Kentish town in north London on 21 November last year.
