Belgium has entered its second day of mourning, following Tuesday’s bombing attack targeting the Brussels Airport and a crowded subway station near the headquarters of the European Union. ISIL has taken responsibility for the attacks, which killed at least 31 people and injured over 230. The bombings took place just days after authorities arrested Salah Abdeslam, a suspect in the November Paris attacks that killed 130 people. On Wednesday, authorities named two Belgian-born brothers with former criminal convictions, Ibrahim and Khalid el-Bakraoui, as suspects in the suicide bombings. Turkish President Tayyip Erdogan said Ibrahim el-Bakraoui was deported last year from Turkey and that Belgium subsequently ignored a warning that the man was a militant. A manhunt is still underway for a third suspect.
