Explosion at Brussels crime lab, no casualties: prosecutors

An explosion at a criminology institute in Brussels early Monday has caused major damage but no casualties, prosecutors and the fire service said. The prosecutors' office declined to speculate on the cause of the explosion at the Institute of Criminology in a Brussels suburb. The explosion occurred with Belgium on high alert after suicide bombers struck Brussels airport and a metro station near the European Union headquarters on March 22, killing 32 people.
