Hicheur allegedly planned to blow up a Total oil refinery. The security source said: “He had offered his services to strike with an active service unit based in France. He had started to compile a precise list of intended targets including a Total oil refinery which would have caused an explosion which would have destroyed a city the size of London.
“Assassination targets including the president and interior minister were also on the list.”
