A knife attack on two Belgian police officers in Brussels on Wednesday is being investigated as a possible terrorist attack, federal prosecutors said.
The officers were attacked at around midday (1000 GMT) in the city's northern commune of Schaerbeek by a man armed with a knife, who has been identified as 43-year-old Hicham D, a Belgian national.
Neither officer is in mortal danger, the prosecution said in a statement. The aggressor was shot in the leg by a third police officer, but also suffered no life-threatening injuries.
"The provisional results of the inquiry indicate that it could be a possible terrorist attack," the statement said, without giving further details.
A judge specialized in terrorist issues is to decide whether the suspect will be detained further.
Also Wednesday, the Gare du Nord train station in the Belgian capital was evacuated during the early afternoon, in what turned out to be a false bomb alert.
