Following Friday's strikes, Vice President JD Vance emphasized that Iran signed a ceasefire agreement and "can pick up the phone" if it has any issues with the memorandum of understanding, in a post on social media.
"Iran signed a ceasefire agreement. We have honored it. If they have disagreements about how the MOU is being applied, they can pick up the phone. But violence will be met with violence," he said.
Vance was in Switzerland earlier this week to negotiate the implementation of the MOU with Iran and mediators.
