A French policewoman was wounded Tuesday during a major Franco-Belgian anti-terror operation in Brussels linked to the Paris attacks, Belgian Justice Minister Koen Geens said.

"It appears the French policewoman who was slightly wounded was here as part of a joint investigation team set up by Belgian and French prosecutors," Geens told a press conference after a dramatic day which saw one suspect shot dead.

Officials said earlier that four police had been hurt in the operation and it was not immediately clear if that included the French officer.
