July 17 (UPI) -- Nicaragua has severed diplomatic relations with Italy after Italian Foreign Minister Antonio Tajani renewed calls for the extradition of Alessio Casimirri, a former member of the militant Red Brigades convicted in Italy for his role in the kidnapping and killing of former Prime Minister Aldo Moro in 1978.

Speaking at an international event organized by the European People's Party in Madrid, Tajani described the government of President Daniel Ortega as "extremist," criticized Nicaragua for sheltering Casimirri and accused it of refusing to over Casimirri to Italian authorities, according to Deutsche Welle.

"We share nothing with the vision of extremist governments such as Nicaragua, a country that protects dangerous Red Brigades terrorists such as Alessio Casimirri, who killed Aldo Moro, one of Italy's most important Christian Democratic politicians. This man lives freely in Nicaragua. That is unacceptable to us," Tajani said.

He added that Italy has not forgotten the victims of terrorism and will continue demanding that Casimirri face justice.
