BRUSSELS — A man wounded two police officers with a knife in Brussels around noon on Wednesday in what the authorities called “a potential terrorist attack.”

The two officers were attacked on the Boulevard Lambermont in the Schaerbeek district, just north of the city center. A third police officer, who came to their aid, was also injured. None of the three had life-threatening injuries.

The man suspected of carrying out the assault was shot in the leg. He was identified only as Hicham D., 43, a Belgian citizen.

“The provisional results of the investigation indicate that it would be a potential terrorist attack,” Eric Van der Sijpt, a spokesman for the federal prosecutor’s office, said in a statement. “The investigating judge specializing in terrorism cases will decide later” about the suspect’s “further detention.”
