Mohammad Javad Zarif criticized Europeans for their false claims by bringing some fact in separate Twitter messages on Wednesday.
In another tweet, Iran's chief diplomat implicitly accused the European Union of inaction and submission to US President Donald Trump's extremist policies.
He also wrote on another tweet that EU3 claims that it has kept its obligations under JCPOA are baseless.
Alleging that Iran is not committed to its obligations, France, Germany and the UK launched the dispute mechanism in the Iran nuclear agreement known as the Joint Comprehensive Plan of Action (JCPOA).
The E3 said it won't impose the unilateral 'maximum pressure' sanctions of US President Donald Trump who withdrew from the deal in 2018. Iran reciprocated by scaling back its commitments under the deal.
