Police found an Islamic State flag next to the body of an Algerian killed during a major anti-terror raid in Brussels, prosecutors said on March 16, as investigators raced to track down two suspected extremists who escaped. Two suspects were still at large after the gunbattle, which erupted as Belgian and French police searched a property in connection with the November Paris massacre claimed by IS in which 130 people died.
