Denmark's defense minister attended a military exercise in Greenland on Monday with his Icelandic and Norwegian counterparts, the Danish defense ministry said, but the United States, which covets the Danish autonomous territory, was absent.

Organized by Denmark, the "Arctic Light 2025" exercise brings together more than 550 troops from NATO allies Denmark, France, Germany, Norway and Sweden.

"The current security situation requires us to significantly strengthen the armed forces' presence in the Arctic and North Atlantic," Danish Defense Minister Troels Lund Poulsen said in a statement.
