KYIV (Reuters) - A bipartisan group of United States senators promised solidarity and weapons on a visit to Kyiv on Monday while warning Russian President Vladimir Putin against launching a new military offensive against Ukraine.

Kyiv and its Western allies have sounded the alarm after Russia massed tens of thousands of troops near Ukraine's borders and pressed the United States for security guarantees, including a block on Ukraine joining the NATO alliance.
