Manchester bomber's younger brother 'was planning an attack on the UN's special envoy to Libya'
The younger brother of Manchester suicide bomber Salman Abedi was planning an attack on a United Nations special envoy.
The Islamic extremist group had been monitored for some months by Libyan security services who believe the younger Abedi brother is a 'significant player, reports the Telegraph.
Twenty two people were murdered and 119 injured when Salman Abedi detonated a nail bomb in his backpack, at an Ariana Grande concert packed full of young people.
The brothers left Britain to visit their parents in Libya after stockpiling the bomb parts, before Salman returned to carry out his deadly mission.
