Giuseppe Paterno, 96, Italy's oldest student, takes his final exam online, for his undergraduate degree that he has been studying for in history and philosophy at the University of Palermo, using a laptop at his home, due to social distancing measures implemented during the coronavirus disease (COVID-19) outbreak, in Palermo, Italy, June 23, 2020. Paterno confessed to a little unease with the video calls that replaced classroom teaching during the coronavirus shutdown, but said he was not put off by the disease itself after the war and everything else he had been through in life. "All of that strengthened us, all of my peer group, all of those who are still alive," he said. "It didn't really scare us that much."

In northern Norway, U.S. Marines train in the ice and snow as they learn how to fight in the freezing cold. The troops are part of a contingent of 650 Marines staging a recent joint military exercise with 3,000 soldiers from NATO-member Norway at a time when both NATO and Russia have increased their military presence in the Arctic. A few hundred kilometres from Setermoen, Russia is modernising its forces on the Kola Peninsula, home to its Northern Fleet. Russia has also carried out manoeuvres in recent weeks, staging a major submarine exercise in the North Atlantic, according to intelligence sources cited by Norwegian media. The rising tension is unsettling many Norwegians, not least in the town of Kirkenes, which for three decades has been trying to foster cooperation with Russia.
