Fans of the Irish hip-hop group Kneecap have assembled outside a court in London for the appearance of one of their members facing a terrorism-related charge.

Liam Óg Ó hAnnaidh, who is charged under the name Liam O’Hanna, is accused of allegedly showcasing a flag in support of the banned group Hezbollah during a performance in London.

The 27-year-old, known in the music world as Mo Chara, is set to appear at Westminster Magistrates’ Court on Wednesday.

In a May statement shared on social media, Kneecap declared: “We contest this supposed ‘offence’ and are prepared to vigorously defend ourselves.”

Supporters gathered outside the courthouse were seen holding signs reading “Free Mo Chara” and “Defend Kneecap.”

Several large green flags bearing the message “Free Speech, Free Palestine” were also present.

Kneecap mentioned that they have “covered” London with supportive messages for their bandmate.

Some members of the crowd waved a combination of Palestinian and Kneecap flags, and cheers erupted when a van passed by displaying the slogan “More Blacks, More Dogs, More Irish, Mo Chara.”
