Italian foreign minister Angelino Alfano told the Italian parliament on Wednesday that Italy will not rest until it uncovers the truth behind the murder in Cairo last year of Italian student Giulio Regeni, ANSA news agency reported.

“We will continue to follow the path of firmness and cooperation, the effort will continue with the same determination there has been up till now,” Alfano said, according to ANSA.

Alfano added that cooperation between Italian and Egyptian prosecutors “has produced fruitful results.”

Regeni was in Cairo to conduct research on independent trade unions when he went missing on 25 January 2016, the fifth anniversary of Egypt’s 2011 Revolution.

His body was found on 3 February on a roadside on the outskirts of Cairo bearing signs of torture.

Egypt has strongly rejected suggestions that security forces were involved in Regeni's murder.

In December, Egypt's prosecutor-general visited Rome to discuss developments in the investigation, the fifth such meeting between Egyptian prosecutors and their Italian counterparts since the murder.
