Northern European nations unite to safeguard offshore infrastructure.

An alliance of northern European nations, including the British-led Joint Expeditionary Force, pledged to step up protection of critical undersea and offshore infrastructure in the face of shared challenges, including alleged Russian ships conducting mapping that indicated "preparations for possible disruption and, at worst, sabotage." The U.K. announced new air defense systems worth 92 million pounds ($116 million) would be bought for Ukraine in coming months "to bolster Ukraine's ability to protect its critical national infrastructure, civilian population, and front-line personnel." The Joint Expeditionary Force is made up of nine NATO nations and Sweden.
