The largest-ever trial of its kind gets underway in Belgium today, over the 2016 terrorist attacks which claimed 32 lives and injured hundreds more in the capital, Brussels.  The landmark case involves ten defendants suspected of carrying out bombings across the city. The New York Times reports that the attacks in France and Belgium were the deadliest operations organized by the Islamic State on European soil, leaving deep wounds and several unanswered questions. The sheer randomness of the violence instilled anxiety across Europe and stoked debate about multiculturalism, immigration, and the place of Islam in largely secular European nations.
