Italy's Senate has voted to stop providing Egypt with free spare parts for its F-16s as a first sanction for what Italy says is a lack of cooperation in investigating the torture and death of an Italian student in Cairo.

Sen. Gian Carlo Sangalli, who pushed the amendment through and secured the 159-55 vote late Wednesday, said he hoped it would "send a signal to Egypt."

Doctoral student Giulio Regeni was abducted in Cairo on Jan. 25. His body, bearing signs of torture, was found nine days later on the side of a suburban Cairo road.

Suspicions have run high in Italy that Egyptian police were behind the death. Egypt has denied any police role.

Egypt's foreign ministry said Thursday it was "dissatisfied" with the vote.
