Police killed on Thursday suspects believed to be involved in the kidnapping of foreigners in the New Cairo district, Egypt's interior ministry announced.
According to the ministry statement, the suspects formed a gang that impersonated police officers to kidnap foreigners with the intent to rob them.
The suspects were killed in a shootout with police, who were attempting to arrest them, the ministry said.
The ministry did not reveal any further details about the suspects or the identity of their victims other than that they were foreigners.
Several news outlets have quoted security sources as saying that the gang is believed to have been involved in the death of Italian student Giulio Regeni, who was found killed in Cairo earlier this year with signs of torture on his body.
However, a security source told Ahram Arabic news website that it has not been confirmed that the group was involved in Regeni's murder, adding that investigations are still underway.
The body of the 28-year-old PhD student, who was conducting research on independent trade union movements in Egypt, was found on a roadside in February, nine days after he disappeared on 25 January.
