US Secretary of State Marco Rubio says that troop shifts by Washington in Europe are not aimed at punishing allies for a lack of support over Iran, AFP reports.

“The United States continues to have global commitments that it needs to meet in terms of our force deployment, and that constantly requires us to reexamine where we put troops. This is not a punitive thing, it’s just something that’s ongoing,” Rubio told reporters ahead of talks in Sweden with his Nato counterparts.
