BRUSSELS (Reuters) - Belgium's chief prosecutor named two brothers on Wednesday as Islamic State suicide bombers who killed at least 31 people in the most deadly attacks in Brussels' history but said another key suspect was on the run.
Tuesday's attacks on a city that is home to the European Union and NATO sent shockwaves across Europe and around the world, with authorities racing to review security at airports and on public transport. It also rekindled debate about lagging European security cooperation and flaws in police surveillance.
