For selling two frigates to Egypt ... Regeni's parents are suing their country's government for violating international law.

The Italian newspaper, La Repubblica, revealed that the parents of the Italian researcher Giulio Regeni, who was killed under torture in Egypt 5 years ago, submitted a complaint against the Italian government accusing it of violating Italian law, by selling two frigates to the Egyptian government.

The newspaper said that the law prohibits the sale of weapons to countries where serious human rights violations are committed, documented by organizations of the United Nations or the European Union.

She added that the decision of Regeni's parents, Claudio and Paula, is now official to file a complaint against the Italian government to investigating judges, who have been investigating for years the circumstances of the death of their son in Egypt.

She added that the complaint included documents proving the violations committed by the Egyptian government, with the testimony of international organizations.

La Repubblica said that what forced Claudio and Paula Regeni to file the complaint was that they considered that the political movement of the Italian government on the Regeni case was insufficient.

This development comes about a month after the Italian Attorney General, Michael Preetipino, charged 4 Egyptian officers with premeditated murder, torture and kidnapping, which the Italian investigations showed that they were involved in the crime, which sparked calls in Italy to cut ties with Egypt and withdraw Italian investments from it.

Later, the Egyptian Public Prosecution issued a statement announcing the temporary closure of the case, and the exclusion of accusations against the Egyptian officers. Rome rejected this announcement, stressing that it would continue to move in international forums to uncover the circumstances of Regeni's death and punish the perpetrators.

And in the middle of last month, Italian Prime Minister Giuseppe Conte announced that a trial in the case of the disappearance and murder of Regeni represents "a way to reach the truth, which is expected to be shocking."

Regeni - who was a PhD student at Cambridge University - in Cairo disappeared in January 2016, and his body was found about a week later, and a forensic examination showed that he had been tortured before his death.
