Brothers suspected in suicide carnage

BRUSSELS — Authorities uncovered bomb material and a farewell message from a suspected suicide bomber Wednesday as details emerged of the Brussels attackers: two brothers who brought chaos and carnage to the city at the heart of European unity. One person was taken into custody, then released, as authorities tried to chase down possible leads for a key suspect on the run: a man whose bomb failed to explode at Brussels Airport. But the brothers — Khalid and Ibrahim el-Bakraoui, both Belgians with criminal records — were identified by authorities as suspected of being among the three suicide bombers who attacked the Brussels metro and airport on Tuesday, claiming at least 31 lives and injuring 270 people.

Question: How can a civilized people fathom than fanaticism that prompts to brothers to give up their lives to murder dozens?
