Jihadis sporting terror group Isis' shirts met in Wales weeks before Nasser Muthana and Reyaad Khan left for Syria, it has emerged.
Need4Khilafah bragged on their Twitter and Facebook pages about the "Muslim summertime cookout 2014" before posting pictures of the event.
The group – suspected of being a front for extremist group Al-Muhajiroun, and which seeks to create an Islamic state in Britain – was banned by the Home Office earlier this week.
