An ISIL flag and a bomb were found at a house in a Brussels district during a search conducted by Belgian police in connection with Tuesday morning blasts, prosecutors said.

The explosive device found at a house in the Schaerbeek municipality contained nails, Belgian prosecutors said. Some chemicals were also found during the search.

Raids are being conducted all across the country in the wake of this morning’s terror attacks, Belgian federal prosecutor Frederic Van Leeuw announced at a press conference. The official added that a possible connection between the Brussels blasts and the Paris attacks is still being investigated.

Three male suspects were captured by CCTV at Brussels Airport before the deadly blasts, the prosecutor said. An image showing the three men has been released.
