European countries that helped broker the 2015 Iran Nuclear Deal are calling on the US to reaffirm its support. They say the deal is essential for international security. It must be signed off every 90 days, and US President Donald Trump has until Friday to decide if he will re-impose sanctions.
Trump has repeatedly threatened to rescind the agreement, which he called "the worst deal ever".
