Sixteen people died in the Gloria funicular derailment in Lisbon, with victims from seven countries and three still unidentified. The dead include five Portuguese, two South Koreans, two Canadians, an American, a Ukrainian, a German, a Swiss national, and the transport brakeman Andre Jorge Goncalves Marques. Four Portuguese victims worked for the Santa Casa da Misericordia NGO and boarded together shortly after 6 p.m. Twenty-two people were injured; nine in serious condition with six in intensive care and 13 discharged.
