BRUSSELS, Aug 29 (Reuters) - A bomb exploded at the Brussels Institute of Criminology in the north of Brussels on Monday but the building was empty and no one was wounded, broadcaster RTL said.

A car rammed through the barriers at about 3 a.m. local time and one or more attackers exploded a bomb near the laboratories which caught fire, RTL said.
