The United States has deployed two aircraft carrier strike groups to the Middle East, positioning its largest regional military presence in decades, as nuclear negotiations with Iran faltered in Geneva this week.
The USS Abraham Lincoln and its accompanying ships arrived in the region more than two weeks ago. The USS Gerald R. Ford, the largest aircraft carrier in the world, is now heading toward the Middle East, according to ship-tracking data and multiple US news outlets.
The two sides held indirect talks in Geneva for three-and-a-half hours on Tuesday, but the session ended with no clear resolution.
