The United States paid over a million euros to the family of Giovanni Lo Porto, an Italian aid worker killed in a U.S. drone strike in January of last year, according to newly released documents. The 37-year-old Lo Porto died when CIA drones struck an al Qaeda compound where he was being held hostage along with Warren Weinstein, an American humanitarian worker. In a rare admission of responsibility, President Barack Obama acknowledged the strike and promised compensation for the families. The Intercept first reported that the family had reached a settlement with the U.S. government in July. The document also states that the agreement does not imply "a waiver of sovereign or personal immunity." Lawyers for the Lo Porto family had pressed the Italian state prosecutor to consider a criminal case against the United States, while acknowledging that the chances of such a case going forward were slim. They also asked for more information from U.S. agencies about the strike and its aftermath. The U.S. has, in a few instances, paid hundreds of thousands of dollars to the families of civilians killed in attacks in Yemen, but has not publicly acknowledged doing so. Many human rights advocacy groups see a double standard in the silence of the U.S. government on the cases of non-Westerners who have died.
