Analysis: Ukraine casts pall over Iran nuke talks

VIENNA (AP) — Tehran may have a new ally when Iran nuclear talks reconvene Tuesday — the Ukraine crisis. U.S.-Russian tensions over Ukraine could fray the search for consensus on what Iran needs to do to ease fears it could make atomic arms.

Both Washington and Moscow are emphasizing that their commitment to eliminating any Iranian proliferation threat overrides their clash over Ukraine. But diplomats tell The Associated Press that Moscow and Washington are wide apart on how much Tehran needs to trim its nuclear program, a split that Iran could exploit.
