OSLO (Reuters) - NATO has not detected any changes to Russia's nuclear forces and the Western alliance has seen no reason to reconsider its own corresponding setup, NATO chief Jens Stoltenberg told a conference in Norway on Thursday.

"We haven't seen any changes in their nuclear forces that trigger us to change our forces and the way those are arranged. So far we haven't seen anything that demands that from our side," Stoltenberg said.
