The 42-year-old, who was capped 22 times, played at the 2007 World Cup in France and scored a try against the hosts to help Argentina finish third.

According to L'Equipe, Aramburu was killed in a drive-by shooting in Paris.

The French newspaper said he had been involved in an early-morning argument in a bar with a group of people who later returned in a car and shot him.

A murder investigation has been opened by the Paris prosecutor's office. Police are reported to be looking for three suspects.

A tribute was paid to Aramburu before France's Six Nations finale against England at Stade de France, with his image shown on the stadium's big screen.

Dimitri Yachvili, former France scrum-half and team-mate of Aramburu at Biarritz, said "the game has lost a brother who loved life".

Aramburu was "always positive, lively and full of energy", Yachvili told the Sud Ouest newspaper.

"More than being a great team-mate, he was a beautiful person who loved rugby."

Aramburu had spells at French clubs Perpignan, Biarritz and Dax before joining Glasgow Warriors in 2010.

The Warriors said they were "shocked and saddened" by Aramburu's "sudden and tragic death".

They added: "The embodiment of a true warrior and much-loved by all, the thoughts of everyone past and present at the club, are with his family at this immensely difficult time."

The Pumas said they "will not forget his tries and his performance" at the 2007 World Cup, where he scored two tries.

Former club Biarritz sent its "most sincere condolences to his family [and] his close relations" and assured them of its "total support".
