Sanctions Iran could face if nuclear talks collapse

The course of international talks over Iran's nuclear program raises the question of whether Congress will once again try to move legislation seeking additional sanctions.

Reportedly, negotiators are looking at putting out a general statement that would continue talks into June toward a final agreement. Initially, lawmakers were waiting until the end of March before deciding whether to move forward on sanctions legislation.

But if they do, and can withstand a presidential veto, Iran could face an array of potential sanctions.

The legislation currently on hold in Congress calls for sanctions to kick in over the course of 2015 if no deal is reached by June. The bill, sponsored by Sens. Mark Kirk, R-Ill., and Bob Menendez, D-N.J., specifically calls for:

• Resuming sanctions currently on hold 
• Closing loopholes in petroleum sanctions 
• Boosting sanctions on Iran's oil trade and financial transactions 
• Imposing new sanctions on top Iranian government officials and other figures 
• Imposing new sanctions on Iran's shipbuilding, automotive, mining and other sectors
